Detected keypoints are less than which is detected by VLFeat #57

Hello! Thanks for your great work first! I don't know why the detected keypoints are less than the keypoints detected by the VLFeat? Can I change some parameters to increase the number of the detected keypoints? Thank you very much!

You could change the threshold according to what is written at the end of the front page. The ideal threshold varies quite a lot depending on the contrasts of the images. The example images are quite high contrast, so the threshold used for those are quite large.
