i wondering if has used daisy features object recognition problems?
link daisy (matlab one) is: http://cvlab.epfl.ch/software/daisy
my question how use software (matlab) keypoints , descriptors? can found out descriptors (in dzy.descs), cannot found keypoints.
i want give try technique object recognition, since, has been written computation fast , produce better result.
thanks lot.
daisy designed dense point matching, means computes descriptor every pixel in image - that's designed do. could retrieve features particular pixels in image using display_descriptor
function described in documentation:
out = display_descriptor(dzy,y,x);
where x
, y
pixel co-ordinates. use keypoint detector of own (e.g. corners, blobs, sift keypoints - see blob detection on wikipedia) decide features extract. should bear in mind not intended use of daisy.
