>Announcing the release of SVEN CV computer vision software... >http://deprogramming.us/sven/software.html > >SVEN CV - the computer vision software used for >SVEN (Surveillance Video Entertainment Network >http://deprogramming.us/sven) - is now available >to the public. The features and interface were >designed specifically for the SVEN project, so >the interface isn't what you might expect from >user-friendly, general purpose software. >However, we hope it can be useful for other >public space projects, as it is specifically >designed to track people in uncontrolled >settings, as opposed to a gallery or stage where >lighting, background, clothing, etc., can be >controlled. > > > > >About SVEN CV... >-------------------------- >SVEN CV is a software application for real time >tracking of pedestrians, using OpenCV. Its >robust build has features for tracking several >individuals with all kinds of foreground and >background occlusions. It also provides >real-time subjective features such as face >detection and expression; hair and clothing >color; segmentation of the body to give >positions for head, shoulders, and torso; >direction of movement and more. It transfers the >data including the coordinates of the person's >outline (matte) to a specified IP address or the >local machine via a UDP port. It supports input >from both live camera and AVI files. > > > >Why? >------- >There are already several computer vision >applications available geared toward "artists." >So why did we bother to develop our own? > >1) We wanted some specific features that weren't >available in existing software. These may or may >not be of use to you. But more importantly... > >2) We wanted it to work in public space. The >SVEN project deals with surveillance, and >surveillance happens in public places: >corridors, storefronts, outside on the street, >etc. The computer vision applications for >artists we found tended to assume a controlled >setting like a gallery or stage, where changes >in lighting and background wouldn't be a >problem. While the best results with SVEN CV are >still obtained with minimal background changes >and reasonably flat, constant lighting, SVEN CV >is designed to adapt to changes in background >and applies heuristics to eliminate as much as >possible errors due to shadows and lighting >changes. > > >License >----------- >Complete licensing information is included in >the Readme. But in general, SVEN CV and its >source code can be used freely for educational, >research and non-profit purposes; however >permission must be obtained for commercial use. > > >SVEN CV software is written by Vincent Rabaud, >developed in coordination with Amy Alexander > >The SVEN project was initiated and directed by >Amy Alexander; Lead Video Developer Wojciech >Kosma; Lead >Computer Vision Developer Vincent Rabaud; >Production Assistan Marilia Maschion. Technical >direction, >utility programming and occasional video programming by Amy Alexander. > >Additional video programming by Jesse Gilbert; >additional computer vision programming by Nikhil >Rasiwasia; additional utility programming by >Cristyn Magnus; additional production assistance >by Annina Rüst. > >SVEN: http://deprogramming.us/sven >SVEN CV: http://deprogramming.us/sven/software.html >
