To crop, you can calculate the top, bottom, left, and right columns of the mask's "true" area by using any(). Then use

croppedImage = fullImage(row1:row2, col1:col2);

or you can use imcrop().

To crop you can use imcrop(), or simply use indexing:

croppedImage = fullImage(row1:row2, col1:col2);

You can use drawcircle() to select a circular region of interest and then create a mask from the ROI. Then you can apply the formula to calculates the contrast value. For example

im = rgb2gray(im2double(imread('peacock.jpg')));
imshow(im);
roi = drawcircle;
mask = createMask(roi);
% formula for contrast value
