I'm trying to extract points of interest to perform an image registration of clinical images. I've detected MSER from an image "I" using vl_mser:

[R, F] = VL_MSER(...)

which returns a region of seeds R and ellipsoids F.

Now I would like to calculate Hog from the ellipsoids' center using vl_hog. However, the input of vl_hog is an image, and I don't know how to extract a HOG from a single pixel (center of ellipsoids).

Thank you!

Computer Vision System Toolbox for MATLAB has a function detectMSERFeatures for detecting MSER regions, and a function extractHOGFeatures for computing the HOG descriptors at given locations.
