Biography

Fleming was educated at New College School and Magdalen College School in Oxford. Thereafter, he was a student at New College, University of Oxford, where he studied for a Bachelor’s degree in Psychology, Philosophy and Physiology. He graduated with First Class Honours in 1999. [4] He then studied for a Doctorate at the Department of Brain and Cognitive Sciences at MIT, graduating in 2004. His doctoral thesis “Human Visual Perception under Real-World Illumination” was supervised by Edward H. Adelson. [5]

In 2003, he took up a post-doctoral research position at the Max Planck Institute for Biological Cybernetics, working in the department of Heinrich H. Bülthoff. [6] From 2009–2013 he served as co-Editor-In-Chief of the journal ACM Transactions on Applied Perception. [7] In 2010, moved to the Justus Liebig University of Giessen to become the Kurt Koffka Junior Professor of Experimental Psychology. [1] From 2013–2016, [8] Fleming coordinated the Marie Curie Initial Training Network “PRISM: Perceptual Representation of Illumination, Shape and Material”. [9] From 2016–2022 he ran the ERC Consolidator Grant “SHAPE: On the Perception of Growth, Form and Process”. [10] He received tenure in 2016 and was promoted to Full Professor in 2020.

Research

Fleming specializes in the human visual perception of materials and objects, and their physical properties. [1] He is particularly known for his contributions to establishing material perception as a field of study in vision science. [15] [17] [18] [19] He uses a combination of research methods from experimental psychology, computational neuroscience, computer graphics and machine learning. [4]

Material Perception

Fleming’s early works focused on the visual perception of the optical properties of surfaces and materials, such as gloss, [20] translucency [21] and transparency. [22] He helped determine the role of visual cues such as motion [23] and binocular stereopsis [24] [25] [26] in the perception of surface reflectance, especially gloss. A recurring theme within this work was the concept that specular reflections behave unlike surface markings—such as pigmentation patterns or scratches—leading to specific visual cues for identifying specular reflections and therefore glossy surfaces. He also investigated how multi-component patterns of specular reflection lead to hazy glossy appearances. [27] His more recent studies on surface appearance have tested whether artificial neural networks can reproduce the patterns of errors and successes that human observers make when judging material properties. [28] [29] [30]

In addition to studying how the visual system estimates optical properties of materials, he has also investigated the relationship between other material properties and material categories, and how these are affected by the viewing distance, as in the so-called ‘material-scale ambiguity’. [31]

Fleming also led a number of studies on how the visual system infers the mechanical properties of materials, such as compliance, [32] elasticity, [33] and viscosity [34] [35] [36] [37] from optical, shape and motion cues. [38] [39] Most of these studies used finite elements computer simulations of liquids or deformable solids interacting with their surroundings. A recurring theme within this body of work is the idea that the visual system represents stimuli in a multi-dimensional space of midlevel visual features, which statistically characterize how shape, motion and appearance evolve over time. He and his colleagues have claimed that such representations facilitate disentangling intrinsic material properties from other factors that also contribute to the proximal stimulus [19] [36] such as a flowing liquid’s speed, or the force deforming a compliant solid.

Early in his career, Fleming argued that the visual system infers material properties through heuristics, using simple image statistics that correlate with surface properties under typical viewing conditions. [5] [20] [21] Later however, he proposed that the visual system uses richer internal models of the appearance of objects and materials under typical viewing conditions—an idea he calls ‘Statistical Appearance Models'. [17] [40] Specifically, he has suggested that the visual system acquires the ability to infer material properties (or other distal stimulus properties) by learning generative models of proximal stimuli through unsupervised learning objectives, such as compressing or predictive coding of image content. [41] [42] A proof-of-concept of this theory was demonstrated by training an unsupervised artificial neural network model on a dataset of computer rendered images of bumpy, glossy surfaces. [43] Fleming and his colleagues found that the model spontaneously learned to disentangle scene variables—such as lighting and surface reflectance—even though it was given no explicit information about the true values of these variables. Moreover, the model correctly predicted both successes and failures (i.e., illusions) of human gloss perception.

Shape Perception

Fleming’s early works focused on the visual estimation of three-dimensional (3D) shape from specular reflections, [44] [45] shading [46] [47] and texture. [48] He is particularly known as a proponent of the role of ‘orientation fields’ in shape perception. [49] [50] Orientation fields refer to spatially varying patterns of the dominant local orientation across the image of a surface, as measured by populations of orientation-selective neurons at each image location. [46] [44] [45] [47] [48] Fleming and his colleagues have shown that local image orientation signals tend to vary smoothly across curved surfaces in ways that are systematically related to 3D shape properties. [51] For textured surfaces, local image orientation is related to first-order shape properties, especially surface slant and tilt. [48] For shading patterns and specular reflections, local image orientation structure is related to second-order shape properties, especially the direction of minimum second derivative of surface depths, and the ratio of minimum and maximum second derivative magnitudes. [44] [47] He has argued that orientation fields provide a fundamental source of information about shape, [52] [53] [54] and that their use by the visual system predicts specific illusions of perceived shape, such as when illumination changes. [55]

In addition to the visual estimation of 3D shape, Fleming has also investigated the perceptual organization of shape [56] [57] and the use of shape to make additional inferences about objects and their properties, [32] [33] [34] [36] [58] —a process he calls ‘Shape Understanding’. [10] Fleming led a number of studies on how the visual system makes inferences about the processes and transformations that have formed objects or altered their shape. [59] [60] [61] [62] [63] [64] [65] A recurring theme within this body of work is that an object’s ‘causal history’ leaves traces in its shape, which can be used to identify which of its features are the result of shape-altering transformations. [60] [62] Such transformations include simple spatial distortions [59] [60] and more complex biological growth processes. [61] By analogy to the visual system’s ability to separate images depicting transparent surfaces into multiple distinct causes, Fleming and his colleagues refer to the separation of shape into distinct causes as ‘Shape Scission’. [65] An example of this is the ability to distinguish the causes of different shape features that occur when a face or object is fully covered with a cloth veil. [66] Some of the visible features of the surface of the cloth are caused by the textile draping of its own accord, while others are due to the protrusion of the underlying object. Observers can distinguish these causes, even when the hidden object is of unknown shape. [66]

Fleming has also investigated the role of shape in object categorization, especially in one-shot learning of novel object categories from a single (or small number of) exemplars. [67] [68] In this context, Fleming and colleagues developed a computational model for predicting the perceived similarity between pairs of two-dimensional (2D) shapes, called ‘ShapeComp’. [69] The model combines a large number of shape features to capture different aspects of shape. He and his colleagues have also studied how shape cues contribute to the visual perception of animacy, [70] and conversely how semantics alter the perceptual organization of shape. [71] Fleming and colleagues have argued that human visual one-shot categorization involves inferring a generative model from the exemplar object. [67] [68] They have proposed that this involves segmenting the object into parts, and representing their relations in a way that can be modified to synthesize novel variants belonging to the same category as the exemplar. They claim that this idea is supported by experiments in which participants are presented with a single exemplar and are asked to draw novel variants. [68]

Computer Graphics

Fleming’s work in computer graphics has mainly focused on perceptually-based approaches to representing and modifying photographic imagery. He contributed to the development of image-based algorithms for altering the material appearance [72] and shape [73] of objects in photographs. His work on orientation fields led to methods for synthesizing images of objects with particular 3D shape and material appearance based on purely 2D image operations. [74] He also contributed to work investigating perceptually-based methods for converting between and presenting conventional (low-dynamic range) and high-dynamic range images. [75] [76] He co-authored a text book entitled “Visual Perception from a Computer Graphics Perspective” [77]

Grasping and interacting with objects and materials

Fleming’s work on motor control has focused primarily on the effects of 3D shape [78] [79] [80] and material properties [79] [81] [82] —including mass, [81] [82] friction [81] [83] and rigidity [84] —on grasping. He and his colleagues have investigated various illusions related to grasping, [82] [85] including the ‘material-weight illusion, [82] a variant of the size-weight illusion, in which the expected weight of an object is manipulated through its surface material (instead of its volume as in the size-weight illusion). He and his colleagues developed a computational model for predicting human precision grip (thumb and forefinger) grasp locations on objects with varying 3D shape and materials properties. [79] The model combines multiple cost functions related to the properties of the object and the actor’s hand. The model predicted average human grasp locations approximately as well as different individuals’ grasps predict one another. His research group has developed methods for measuring the contact regions between hands and objects to capture unconstrained, whole-hand grasping behavior. [86]

The visual cortex of the brain is the area of the cerebral cortex that processes visual information. It is located in the occipital lobe. Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex. The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 (V1), Brodmann area 17, or the striate cortex. The extrastriate areas consist of visual areas 2, 3, 4, and 5.

<span class="mw-page-title-main">Shape</span> Form of an object or its external boundary

A shape is a graphical representation of an object's form or its external boundary, outline, or external surface; it is distinct from other object properties, such as color, texture, or material type. In geometry, shape excludes information about the object's location, scale, orientation and reflection. A figure is a representation including both shape and size.

<span class="mw-page-title-main">Binocular vision</span> Type of vision with two eyes facing the same direction

In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and shares no field of view between them, like in some animals.

<span class="mw-page-title-main">Peripheral vision</span> Area of ones field of vision outside of the point of fixation

Peripheral vision, or indirect vision, is vision as it occurs outside the point of fixation, i.e. away from the center of gaze or, when viewed at large angles, in the "corner of one's eye". The vast majority of the area in the visual field is included in the notion of peripheral vision. "Far peripheral" vision refers to the area at the edges of the visual field, "mid-peripheral" vision refers to medium eccentricities, and "near-peripheral", sometimes referred to as "para-central" vision, exists adjacent to the center of gaze.

<span class="mw-page-title-main">Ambiguous image</span> Image that exploits graphical similarities between two or more distinct images

Ambiguous images or reversible figures are visual forms that create ambiguity by exploiting graphical similarities and other properties of visual system interpretation between two or more distinct image forms. These are famous for inducing the phenomenon of multistable perception. Multistable perception is the occurrence of an image being able to provide multiple, although stable, perceptions.

The Chubb illusion is an optical illusion or error in visual perception in which the apparent contrast of an object varies substantially to most viewers depending on its relative contrast to the field on which it is displayed. These visual illusions are of particular interest to researchers because they may provide valuable insights in regard to the workings of human visual systems.

<span class="mw-page-title-main">Fixation (visual)</span> Maintaining ones gaze on a single location

Fixation or visual fixation is the maintaining of the gaze on a single location. An animal can exhibit visual fixation if it possess a fovea in the anatomy of their eye. The fovea is typically located at the center of the retina and is the point of clearest vision. The species in which fixational eye movement has been verified thus far include humans, primates, cats, rabbits, turtles, salamanders, and owls. Regular eye movement alternates between saccades and visual fixations, the notable exception being in smooth pursuit, controlled by a different neural substrate that appears to have developed for hunting prey. The term "fixation" can either be used to refer to the point in time and space of focus or the act of fixating. Fixation, in the act of fixating, is the point between any two saccades, during which the eyes are relatively stationary and virtually all visual input occurs. In the absence of retinal jitter, a laboratory condition known as retinal stabilization, perceptions tend to rapidly fade away. To maintain visibility, the nervous system carries out a procedure called fixational eye movement, which continuously stimulates neurons in the early visual areas of the brain responding to transient stimuli. There are three categories of fixational eye movement: microsaccades, ocular drifts, and ocular microtremor. At small amplitudes the boundaries between categories become unclear, particularly between drift and tremor.

The visual appearance of objects is given by the way in which they reflect and transmit light. The color of objects is determined by the parts of the spectrum of light that are reflected or transmitted without being absorbed. Additional appearance attributes are based on the directional distribution of reflected (BRDF) or transmitted light (BTDF) described by attributes like glossy, shiny versus dull, matte, clear, turbid, distinct, etc. Since "visual appearance" is a general concept that includes also various other visual phenomena, such as color, visual texture, visual perception of shape, size, etc., the specific aspects related to how humans see different spatial distributions of light have been given the name cesia. It marks a difference with color, which could be defined as the sensation arising from different spectral compositions or distributions of light.

Visual perception is the ability to interpret the surrounding environment through photopic vision, color vision, scotopic vision, and mesopic vision, using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees. A person can have problems with visual perceptual processing even if they have 20/20 vision.

Form perception is the recognition of visual elements of objects, specifically those to do with shapes, patterns and previously identified important characteristics. An object is perceived by the retina as a two-dimensional image, but the image can vary for the same object in terms of the context with which it is viewed, the apparent size of the object, the angle from which it is viewed, how illuminated it is, as well as where it resides in the field of vision. Despite the fact that each instance of observing an object leads to a unique retinal response pattern, the visual processing in the brain is capable of recognizing these experiences as analogous, allowing invariant object recognition. Visual processing occurs in a hierarchy with the lowest levels recognizing lines and contours, and slightly higher levels performing tasks such as completing boundaries and recognizing contour combinations. The highest levels integrate the perceived information to recognize an entire object. Essentially object recognition is the ability to assign labels to objects in order to categorize and identify them, thus distinguishing one object from another. During visual processing information is not created, but rather reformatted in a way that draws out the most detailed information of the stimulus.

Binocular switch suppression (BSS) is a technique to suppress usually salient images from an individual's awareness, a type of experimental manipulation used in visual perception and cognitive neuroscience. In BSS, two images of differing signal strengths are repetitively switched between the left and right eye at a constant rate of 1 Hertz. During this process of switching, the image of lower contrast and signal strength is perceptually suppressed for a period of time.

Visual crowding is the inability to view a target stimulus distinctly when presented in a clutter. Crowding impairs the ability to discriminate object features and contours among flankers, which in turn impairs people's ability to respond appropriately to the target stimulus.

In psychology and neuroscience, multiple object tracking (MOT) refers to the ability of humans and other animals to simultaneously monitor multiple objects as they move. It is also the term for certain laboratory techniques used to study this ability.

Ensemble coding, also known as ensemble perception or summary representation, is a theory in cognitive neuroscience about the internal representation of groups of objects in the human mind. Ensemble coding proposes that such information is recorded via summary statistics, particularly the average or variance. Experimental evidence tends to support the theory for low-level visual information, such as shapes and sizes, as well as some high-level features such as face gender. Nonetheless, it remains unclear the extent to which ensemble coding applies to high-level or non-visual stimuli, and the theory remains the subject of active research.

Vergence-accommodation conflict (VAC), also known as accommodation-vergence conflict, is a visual phenomenon that occurs when the brain receives mismatching cues between vergence and accommodation of the eye. This commonly occurs in virtual reality devices, augmented reality devices, 3D movies, and other types of stereoscopic displays and autostereoscopic displays. The effect can be unpleasant and cause eye strain.
