dist ratio and patch radius

[clelouch]

Hi, thanks for your code! After reading the code and your paper, I have some questions.

1. You wrote in your paper that you do not enforce the ratio test by pruning descriptors whose top-ranked nearest neighbors are very similar. However, in you code, the MATCH_MAX_DIST_RATIO is set to 0.8. If I'm not wrong, we should set it to 1.0 ?
2. In your code, the PATCH_RADIUS is set to 32. However, the feature_extraction_tfeat.py use patches31. I wonder if I should resize the generated patches to 31 pixels or I should set the radius to 15 pixels? @ahojnnes Thanks for your help!
