Corner detection on a subpart of an image

Hi
I would like to do corner detection on a subpart of an image using Computer Vision System Toolbox. For example using:
% FAST algorithm by Rosten & Drummond
hCornerDet = vision.CornerDetector('Method','Local intensity comparison (Rosten & Drummond)');
pts = step(hCornerDet, I);
I can get the allowed pixels from regionprops or use ginput() to get the corners of the region to do corner detection on.
I don't want to search the whole image and remove detected corners outside the wanted area afterwords.
Any suggestions?

I suggest you explain better what "remove" means. Does that mean that you want to set those pixels to black?
