Hello,
I have written my Java code for the detection of keypoints using SIFT, as follows:
FeatureDetector featureDetector = FeatureDetector.create(FeatureDetector.SIFT);
MatOfKeyPoint keypoints = new MatOfKeyPoint();
featureDetector.detect(image, keypoints);
where image is a Mat variable containing the image.
However, I am not sure how to compute the dense SIFT descriptors, as contained in the PHOW computation of the VLFeat library. Is there a way of doing this?
Thank you in advance.
