Hello, I'm doing a project on matching sketches with photos. I'm using SURF descriptor for feature extraction from facial image. those resultant features are used for classification.But surf descriptor extracts the features on whole image. I want to extract features from specific points like eye corner, nose tip, mouth etc. How to select those points on the facial image and do extraction...Please help me out
Thank you

What if you just mask out the part of the image you don't care about, like if you use a binary image
grayImage(mask) = 250; % Or whatever white value you want to erase the image.
