York University: York University (French: "Université York" ) is a public research university in Toronto, Ontario, Canada.  It is Canada's third-largest university.

Allen Taylor (scientist): Allen Taylor is an American scientist and Professor of Nutrition, Development, Molecular and Chemical Biology, and Ophthalmology.  He is the Senior Scientist and Director of the Laboratory for Nutrition & Vision Research (LNVR) at the Human Nutrition Research Center on Aging.  Dr. Taylor also founded and directs the Science Training Encouraging Peace Graduate Training Program (STEP-GTP), which pairs Israeli and Palestinian advanced level health science students in the same graduate training program in an effort to foster sustainable, cooperative relationships that advance the careers of the STEP Fellows and provide improved health care in the communities they serve.  Thus, STEP endeavors to build bridges for productive and cooperative living between the STEP Fellows and the communities.

John Tsotsos: John Tsotsos is a Canadian Computer Scientist whose research focuses on the field of Computer Vision.  He is best known for his work in visual attention, specifically for establishing the need for visual attention through an argument from computational complexity and subsequently developing a computational framework for neuronal attention known as the Selective Tuning model.  He is currently the Canada Research Chair in Computer Vision at York University and served as the Director of the Centre for Vision Research at York University from 2000-2006.  He was elected to the Royal Society of Canada in 2010.

Michael F. Cohen: Michael F. Cohen is an American computer scientist and researcher in computer graphics.  He was a Senior Research Scientist at Microsoft Research for 21 years until he joined Facebook Research in 2015.  In 1998, he received the ACM SIGGRAPH CG Achievement Award for his work in developing radiosity methods for realistic image synthesis.  He was elected a Fellow of the Association for Computing Machinery in 2007 for his "contributions to computer graphics and computer vision."

BMVA Summer School: BMVA Summer School is an annual summer school on computer vision, organised by the British Machine Vision Association and Society for Pattern Recognition (BMVA).  The course is residential, usually held over five days, and consists of lectures and practicals in topics in image processing, computer vision, pattern recognition.  It is intended that the course will complement and extend the material in existing technical courses that many students/researchers will encounter in their early stage of postgraduate training or caeeers.  It aims to broaden awareness of knowledge and techniques in Vision, Image Computing and Pattern Recognition, and to develop appropriate research skills, and for students to interact with their peers, and to make contacts among those who will be the active researchers of their own generation.  It is open to students from both UK and non-UK universities.  The registration fees vary based on time of registration and are in general slightly higher for non-UK students.  The summer school has been hosted locally by various universities in UK that carry out Computer Vision research, e.g., Kingston University, the University of Manchester and Swansea University.

McCarthy Formalism: In computer science and recursion theory the McCarthy Formalism (1963) of computer scientist John McCarthy clarifies the notion of recursive functions by use of the IF-THEN-ELSE construction common to computer science, together with four of the operators of primitive recursive functions: zero, successor, equality of numbers and composition.  The conditional operator replaces both primitive recursion and the mu-operator.

Ronald Silverman: Ronald H. Silverman is currently Professor of Ophthalmic Science at Columbia University Medical Center.  He is currently the director of the CUMC Basic Science Course in Ophthalmology, which takes place every January at the Harkness Eye Institute.  He departed Weill Cornell Medical College in 2010, where he was Professor of Ophthalmology as well as a Dyson Scholar and the Research Director of the Bioacoustic Research Facility, Margaret M. Dyson Vision Research Institute at Weill Cornell.  Dr. Silverman holds an M.S. in Bioengineering from the Polytechnic Institute of New York, and a Ph.D. in Computer Science from Polytechnic University.  He is also a Member of the Research Staff at the Frederic L. Lizzi Center for Biomedical Engineering, Riverside Research Institute.

Longuet-Higgins Prize: The Longuet-Higgins Prize is an award given annually by the Technical Committee on Pattern Analysis and Machine Intelligence of the IEEE Computer Society at the IEEE Conference on Computer Vision and Pattern Recognition (CVPR), for 'Fundamental contributions in Computer Vision'.  The award recognizes CVPR papers from ten years ago that have made a significant impact on computer vision research.  The award is named after theoretical chemist and cognitive scientist H. Christopher Longuet-Higgins.
