CS 664: Problem Set 2 : Motion and Snakes

A postscript copy of the assignment.

New Test Images. Here is another set of images, with corresponding squared-gradient magnitude image. Be sure to read mini-FAQ below. I've also recomputed the coke-can image, there seemed to be problems with its sg image. These images are also available in ~jmiller/test2 on the cs and sunlab machines. I would prefer that you just create symbolic links to the images if you can, since they exceed 3MB. "ln -s ~jmiller/test2 ."

Test Images. Here is the first set of images, available in a tar file. There are two sets of stereo images that you can use to test your motion calculations. There is a sequence called dots that is a moving box on a random background. There is also the coke-can images along with the dx,dy, and squared gradient magnitude images for the coke can. You can use the squared gradient magnitude image as a simple external energy field for snakes that are attracted to edges.

For you Sun users on the cs filesystems, feel free to use ~robotlab/bin/drawsnake or markpoints to draw your initial snakes. (Also available on the sunlab in ~jmiller/664/ps2).
