The prime advantage gait of gait as a biometric is that it can be used for recognition at a distance whereas other biometrics cannot. There is a rich selection of approaches and many advances have been made, as will be reviewed in this talk. Soft biometrics is an emerging area of interest in biometrics where we augment computer vision derived measures by human descriptions. Applied to gait biometrics, this again can be used where other biometric data is obscured or at too low resolution. The human descriptions are semantic attributes and are a set of labels which are converted into numbers. Naturally, there are considerations of language and psychology when the labels are collected, giving our attributes greater precision than those used generally in computer vision. After describing current progress in gait biometrics, this talk will describe how the soft biometrics attributes are collected, and how they can be used to enhance recognising people by the way they walk. As well as reinforcing biometrics, this approach might lead to a new procedure for collecting witness statements, and to the ability to retrieve subjects from video using witness statements and is thus another computer vision approach to image retrieval.
Mark Nixon is the Professor in Computer Vision at the University of Southampton UK where he has worked since being awarded a PhD in 1982. His research interests are in image processing and computer vision. His team develops new techniques for static and moving shape extraction which have found application in automatic face and automatic gait recognition and in medical image analysis. His team were early workers in face recognition, later came to pioneer gait recognition and more recently joined the pioneers of ear and soft biometrics. His vision textbook, with Alberto Aguado, Feature Extraction and Image Processing (Academic Press) reached 3rd Edition in 2012 and has become a standard text in computer vision. With Tieniu Tan and Rama Chellappa, their book Human ID based on Gait is part of the Springer Series on Biometrics and was published in 2005. He has chaired/ program chaired many conferences and given many invited talks. Mark is a member of IAPR TC4 Biometrics and of the IEEE Biometrics Council. Dr. Nixon is a Fellow IET and FIAPR.
