Monday, June 14, 2010 - 8:30am - 6:00pm

The Open Source Vision Software, Intro and Training CVPR 2010 tutorial aims at introducing computer vision students and researchers to a selection of open source computer vision packages. The emphasis is on problem solving, with demos illustrating how to apply the software to relevant computer vision problems. It will be discussed how the open source approach fosters learning, reproducible research, and scientific collaboration.

Organizers:

• Andrea Vedaldi, Brian Fulkerson (Oxford & UCLA - VLFeat)
• Hailin Jin, Lubomir Bourdev (Adobe Systems - Generic Image Library)
• Gary Bradski, Vadim Pisarevsky, Radu Bogdan Rusu (Willow Garage - OpenCV, ROS, PCL)

Slides

• VLFeat library tutorial slides
• Using GIT to track third party projects tutorial slides
• GIL tutorial slides by Hailin Jin
• GIL tutorial slides by Lubomir Bourdev
• OpenCV and ROS tutorial slides
• ROS slides, PCL slides, PCL features slides
