A little improvement

To continue debugging the correspondence issue, I tested with images that had been cropped to contain a small portion of the original image. See correspondence results below.The correspondences here are good, so the SIFT correspondences obviously work ok for this type of image. For images containing more of the original scene, I tried varying the threshold parameter of the matching function. A higher threshold seems to work better, see results below.

This did improve the quality of the correspondences. However, there are hardly no correspondences on the foreground object (the person and the bike), so this might make the motion segmentation method fail.

  1. Hi Arturo,

    This is Kedar from cse 190. Could you email me the motion layer code that we were talking about in class? I think we could benifit from it.
