Hi,
I'm using points = detectSURFFeatures(I) for feature detection. I can use a rectangular ROI with this funstion in the format of [x y w h], however I need to use an arbitory ROI(from a mask with out any typical shape). Is it possible to use detectSURFFeatures function with an arbitory ROI?? The resean is that when I chose rectangle still there are some locations that are inrelavant. Any help would be appreciated.
Regards,

Unfortunately, rectangle is the only type of ROI supported. As a workaround, you can define multiple ROIs in your image to cover the relevant area, extract feature points separately, and then combine the points.
