I am working on a medical images dataset. The problem I am facing is that the region of interest is present in different parts in all images. What I want is to extract the features from an image only from that particular region of interest. I do not want to do the cropping as it will degrade the quality of the ROI. I want to first tell the computer that it is the particular area (but this measurement of area must be same for all the images) from which I want to extract the features and with the help of a suitable feature descriptor I will extract the features?Would sliding window work? If yes then how? Please help me with this. Thanks in advance!!!!

Hii, just got to know that I can use imfreehand() to draw the roi on the image that's what I wanted to tell the computer
That means you manually use the imfreehand() to segment all images invividually?
