I am trying to use feature detection (KAZE) for a perticular section in my image. For now I have been cropping the image to only detect/extract features from the intended section. Placing the cropped out section back in the image is supposed to be next step for me now.
But, is there a way to specify a search region without altering (cropping) the image? So that the detect/extract kaze features only works in that region and also the match feature command also.
Thank you

You can specify the ROI that you want to extract features from.

Somehow I skipped over this in the help section. Thank you for pointing it out.
