Mark S. Nixon is an author,researcher,editor and an academic. He is the former president of IEEE Biometrics Council,and former vice-Chair of IEEE PSPB. He retired from his position as Professor of Electronics and Computer Science at University of Southampton in 2019. [1]
Nixon’s main research interests include using gait and ear as biometrics and using soft biometrics for identification. He has served the International Association for Pattern Recognition (IAPR) in several offices. Nixon has authored 4 books including Feature Extraction and Image Processing for Computer Vision,Human Identification based on Gait and Introductory Digital Design. He has around 20,000 citations. [2]
Nixon became a BMVA Distinguished Fellow in 2015. [3] He is a Fellow of the International Association of Pattern Recognition. [4]
Nixon graduated from University of Reading in BSc Cybernetics Science with Subsidiary Mathematics in 1979. He completed his doctoral studies in Applied Estimation Theory from the same university in 1983. [5]
Nixon joined University of Southampton in 1983 and became a Professor of Electronics and Computer Science;he was awarded Personal Chair in 2001 and retired in 2019. [5]
Nixon has held several leadership and management positions over the course of his career. He was appointed as President of the IEEE Biometrics Council from 2017 to 2018. He was appointed as Chair of the International Association of Pattern Recognition (IAPR),while also serving as member of Nominating Committee and Advisory Committee. He has been serving as the vice-Chair IEEE PSPB since 2018. He is an advisory editor for Pattern Recognition Letters. [6]
Nixon’s research on biometrics and computer science has continued nearly 40 years,pioneering human gait as a biometric and joining the pioneers of the use of ears in biometrics. In his initial work with face recognition,his team applied new techniques for shape extraction and description and more recently formulated them for moving objects. This research is also applied to medical imagery and in remotely–sensed image analysis. Nixon’s research approaches operate on spatial images,video and in 3D. [7]
Nixon's later research was focused on mechanisms that seek to cross the semantic gap and to learn human descriptions from computer vision features and conversely to learn image features from human descriptions;also using soft biometrics where the use of human descriptions for biometrics purpose is pioneered. In the recent years,Nixon and his team have described how subjects can be recognized by human descriptions (attributes) of their body,face and their clothing. [8] Nixon’s work of fusion of soft biometrics leads to the identification and search for subjects in video material and also has an impact on the eyewitness procedures. [9]
Nixon has also worked into developing a new approach to analyze acceleration in image sequences based on the fact that most approaches to analyzing velocity actually subsume many types of motion. By separating out acceleration,a new capability can be observed,e.g. rotational acceleration to find a walking subject’s feet,as well as new capability to detect violent actions since acceleration is innate to such acts. [10]
Nixon was featured in the IAPR newsletter [11] and in ‘Biometric Technology Today’in 2016. His work received extensive media coverage in 2018 when it was applied in an egregious case in Australia to identify a subject who cased a shop and then murdered its owner. [12]
Nixon’s book Feature Extraction and Image Processing for Computer Vision published in 2002 was the first book concentrating solely on the topic. He was awarded the Notable Book Award by the Computing Reviews in 2012 for his work in the book. According to Elisa Smith from IAPR newsletter,the book contains “a broad overview of the field presented at a level of depth aimed at those who are new to the field”. The book is praised for its citation of “an overwhelming and impressive number of books,conference,and journal articles on a broad range of topics”. She also stated that this book could be used “as a good framework to facilitate a broad range of discussion topics”. [13]
Computer vision tasks include methods for acquiring,processing,analyzing and understanding digital images,and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information,e.g. in the forms of decisions. Understanding in this context means the transformation of visual images into descriptions of the world that make sense to thought processes and can elicit appropriate action. This image understanding can be seen as the disentangling of symbolic information from image data using models constructed with the aid of geometry,physics,statistics,and learning theory.
Handwriting recognition (HWR),also known as handwritten text recognition (HTR),is the ability of a computer to receive and interpret intelligible handwritten input from sources such as paper documents,photographs,touch-screens and other devices. The image of the written text may be sensed "off line" from a piece of paper by optical scanning or intelligent word recognition. Alternatively,the movements of the pen tip may be sensed "on line",for example by a pen-based computer screen surface,a generally easier task as there are more clues available. A handwriting recognition system handles formatting,performs correct segmentation into characters,and finds the most possible words.
Biometrics are body measurements and calculations related to human characteristics. Biometric authentication is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance.
Gait analysis is the systematic study of animal locomotion,more specifically the study of human motion,using the eye and the brain of observers,augmented by instrumentation for measuring body movements,body mechanics,and the activity of the muscles. Gait analysis is used to assess and treat individuals with conditions affecting their ability to walk. It is also commonly used in sports biomechanics to help athletes run more efficiently and to identify posture-related or movement-related problems in people with injuries.

Multilinear subspace learning is an approach for disentangling the causal factor of data formation and performing dimensionality reduction. The Dimensionality reduction can be performed on a data tensor that contains a collection of observations have been vectorized,or observations that are treated as matrices and concatenated into a data tensor. Here are some examples of data tensors whose observations are vectorized or whose observations are matrices concatenated into data tensor images (2D/3D),video sequences (3D/4D),and hyperspectral cubes (3D/4D).
