CafeLitt 168: 3D perception in Brain

Thu 13 May 2010, 19:00, by Dr. Shahin Zangenehpour (PhD), at Bistro Burritoville:3rd floor, 2055 Rue Bishop, Montreal,QC (Map)
(This talk will be presented in English) 
The human visual system is equipped with a remarkable capacity to extract and represent depth information from flat images cast on the back of each eye. This aspect of visual perception is integral to representing the relative location and structural properties of objects in the field of view. Advances in understanding how this phenomenon unfolds in the conscious mind have led to the advent of technologies that allow us to see 3-dimensional (3D) images presented on flat cinema and/or television screens. The entertainment industry which is a major component of Western culture has had a recent history of success using this technology to attract viewers to movie theatres and to market home entertainment units capable of presenting 3D content. I will present an overview of the basics of visual depth perception and use this as a foundation for explaining how 3D content presentation works in order to create "realistic" visual experience in modern entertainment.

About us

CaféLitt is not a place; it is a gathering of minds. We are a group of mostly Persian young students, scholars and professionals who gather every Thursday evening around 19h00 to discuss various subjects and share different ideas, ranging vastly from history to science, from literature to fine arts. We started these gatherings on Jan 17th, 2006 with 5 people and have reached an average weekly audience of about 40 people. Each week, one of us takes the responsibility of presenting a topic for about an hour in a subject s/he is intimately familiar with or has an expertise in. Afterwards, the evening turns into a discussion forum and all members of the audience will have an opportunity to ask their question(s) and share their points of view.

Some new and exciting ideas were born out of CaféLitt sessions. We have started a series of monthly meetings called CaféCinema during which a movie is presented and discussed in some detail afterward. This year's program of CaféCinema revolves around the history of Iranian cinema. Some Cinema students hold these sessions (mainly conducted in English) on the last Sunday of each month.

Likewise, CaféLitt BookClub is an activity where people who like books decide to read a book each month and discuss it during a cozy Café session on the second Sunday of every month.

CaféTheatre is a series of semi-rehearsed sessions in which we select a play, divide the roles among different people and read the play from the text in front of an audience. Similar to other CaféLitt sessions, each CaféTheatre session will end with a discussion of that day's play.  

CaféScience and CaféPhilo are our plans for near future. The purpose of CaféScience is to provide a forum for the public discussion and understanding of all scientific findings and ideas, with an emphasis on new, interesting and publicly relevant topics. During CaféPhilo sessions, we will talk about philosophy, its history and all its related aspects.

CaféLitt is pen to all comments, suggestion and new ideas. CaféLitt provides an unparalleled opportunity for learning about culture, science and philosophy in a relaxed and friendly environment, and for sharing your knowledge and expertise with like-minded members of your community.

CafeLitt is a nonpartisan, nonreligious and nonpolitical entity.
