Hi, I am new to matlab. I am trying to extract pixel data of a particular region (ROI defined by the user) in order to characterise that region. But I only want to extract this ROI and remove all other pixels. Any recommended approaches/code?

You can extract pixel data of a particular region by using IMCROP function.
For example,
I= imread('example.png');
imshow(I);
rect = [290 160 220 165];
I2= imcrop(I,rect);
figure
imshow(I2);
