I am using SIFT features for detecting logos in clothes. SIFT is quite powerful, as it is scale invariant, but how do I deal with the problem of occlusion and warping?

More specifically, the logos in clothes might be partially occluded, and can also be warped when the clothes are stretched or squeezed.

Any suggestion and directions? Thanks in advance!

Some example are showed here:

  • $\begingroup$ You might need to generate lots of images synthetically to get enough data. I don't know, it's not something I've done. I thought your answer might help someone help you. Another possibility is multiscale sliding window like HOG (again you need lots of data), but why don't you try the SIFT and see? $\endgroup$ – D.J.Duff Feb 5 '15 at 20:32
