Wolfgang Heidrich is a German-Canadian computer scientist and Professor at the King Abdullah University of Science and Technology (KAUST), for which he served as the director of Visual Computing Center [1] from 2014 to 2021. He was previously a professor at the University of British Columbia (UBC), where he was a Dolby Research Chair [2] (2008-2013). His research has combined methods from computer graphics, optics, machine vision, imaging, inverse methods, and perception to develop new Computational Imaging and Display technologies. His more recent interest focuses on hardware-software co-design of the next generation of imaging systems, with applications such as high dynamic range (HDR) imaging, [3] [4] [5] compact computational cameras, [6] [7] hyper-spectral cameras, [8] [9] wavefront sensors, [10] [11] to name just a few.

Heidrich is best known for his work in developing the high dynamic range (HDR) imaging and displays, which served as the basis for the technology behind Brightside Technologies, [12] which was acquired by Dolby in 2007, and then later on (as part of the Dolby vision) turned into one of the core technical solutions for commercial displays. [13] [14]

In 2010, Heidrich, along with Erik Reinhard, Paul Debevec, Sumanta Pattanaik, Greg Ward, and Karol Myszkowsk, published the book High Dynamic Range Imaging: Acquisition, Display, and Image-Based Lighting, [15] that later on became an essential resource for people working with images. [16]

Heidrich was presented AAIA [17] Fellow, IEEE Fellow, and Eurographics [18] Fellow in 2022, 2021, and 2013, respectively. He is the recipient of the ACM SIGGRAPH Computer Graphics Achievement Award [19] (2023), the Humboldt Research Award [20] (2014), the Charles A. McDowell Award for Excellence in Research [21] (2011), an NSERC Discovery Accelerator Supplement [22] (2010), and the Peter Wall Institute for Advanced Studies Early Career Scholar Award (2002).

Biography

Heidrich received his Diplom informatiker from University of Erlangen (1995), an M.Math in computer science from University of Waterloo (1996), and a PhD (with honours) in computer science from University of Erlangen (1999). Before joining UBC, he was a Research Associate at Max-Planck-Institute for Computer Science (1999-2000). Then, he became a faculty member at the University of British Columbia (UBC) computer science (2000-2018). Since 2014, he has been affiliated with King Abdullah University of Science and Technology (KAUST) CS and ECE.

<span class="mw-page-title-main">Rendering (computer graphics)</span> Process of generating an image from a model

Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene. The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output.

<span class="mw-page-title-main">Multi-exposure HDR capture</span> Technique to capture HDR images and videos

In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images by taking and combining multiple exposures of the same subject matter at different exposure levels. Combining multiple images in this way results in an image with a greater dynamic range than what would be possible by taking one single image. The technique can also be used to capture video by taking and combining multiple exposures for each frame of the video. The term "HDR" is used frequently to refer to the process of creating HDR images from multiple exposures. Many smartphones have an automated HDR feature that relies on computational imaging techniques to capture and combine multiple exposures.

The light field is a vector function that describes the amount of light flowing in every direction through every point in space. The space of all possible light rays is given by the five-dimensional plenoptic function, and the magnitude of each ray is given by its radiance. Michael Faraday was the first to propose that light should be interpreted as a field, much like the magnetic fields on which he had been working. The phrase light field was coined by Andrey Gershun in a classic 1936 paper on the radiometric properties of light in three-dimensional space.

<span class="mw-page-title-main">3D display</span> Display device

A 3D display is a display device capable of conveying depth to the viewer. Many 3D displays are stereoscopic displays, which produce a basic 3D effect by means of stereopsis, but can cause eye strain and visual fatigue. Newer 3D displays such as holographic and light field displays produce a more realistic 3D effect by combining stereopsis and accurate focal length for the displayed content. Newer 3D displays in this manner cause less visual fatigue than classical stereoscopic displays.

Non-photorealistic rendering (NPR) is an area of computer graphics that focuses on enabling a wide variety of expressive styles for digital art, in contrast to traditional computer graphics, which focuses on photorealism. NPR is inspired by other artistic modes such as painting, drawing, technical illustration, and animated cartoons. NPR has appeared in movies and video games in the form of cel-shaded animation as well as in scientific visualization, architectural illustration and experimental animation.

<span class="mw-page-title-main">High-dynamic-range rendering</span> Rendering of computer graphics scenes by using lighting calculations done in high-dynamic-range

High-dynamic-range rendering, also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer-generated movies and special effects benefit from this as it creates more realistic scenes than with more simplistic lighting models.

<span class="mw-page-title-main">Autostereoscopy</span> Any method of displaying stereoscopic images without the use of special headgear or glasses

Autostereoscopy is any method of displaying stereoscopic images without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D". There are two broad approaches currently used to accommodate motion parallax and wider viewing angles: eye-tracking, and multiple views so that the display does not need to sense where the viewer's eyes are located. Examples of autostereoscopic displays technology include lenticular lens, parallax barrier, and may include Integral imaging, but notably do not include volumetric display or holographic displays.

High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a dynamic range higher than usual.

<span class="mw-page-title-main">Femto-photography</span>

Femto-photography is a technique for recording the propagation of ultrashort pulses of light through a scene at a very high speed (up to 1013 frames per second). A femto-photograph is equivalent to an optical impulse response of a scene and has also been denoted by terms such as a light-in-flight recording or transient image. Femto-photography of macroscopic objects was first demonstrated using a holographic process in the 1970s by Nils Abramsson at the Royal Institute of Technology (Sweden). A research team at the MIT Media Lab led by Ramesh Raskar, together with contributors from the Graphics and Imaging Lab at the Universidad de Zaragoza, Spain, more recently achieved a significant increase in image quality using a streak camera synchronized to a pulsed laser and modified to obtain 2D images instead of just a single scanline.
