bob.ip.VLDSIFT doesn't extract feature every time
Created by: zongyuange
Hi, I have encountered a problem for this function. When I setup a feature extractor as:
im = bob.io.load('10.jpg'); im_r = im[0,:,:]; im_g = im[1,:,:]; sift_ex = bob.ip.VLDSIFT(309,372,1,3); # 309 and 372 is the image height and width sift_r = sift_ex(numpy.float32(im_r)); sift_g = sift_ex(numpy.float32(im_g));
Then I will find sift_g value starts from [28000:end] all equals to zero. If you apply this sift feature extractor to im_r again, same thing happened to sift_r. I have attached the image for you to have a look. Thanks!
