hello everyone I need help. I have a picture consisting only of black and white. Does anybody know of any function which I figured would be an area of white on obazku.
Thank you so much to everyone

solution to my problem was easier than it seemed ...
A=[0 1 0 0 0 0 1; 1 0 1 0 1 1 0; 0 0 1 1 1 0 1]
figure, imshow(A)
B = sum(sum(A))

Do you want just the total number of pixels of white? If so, just sum the image (sum all 1's).
If you want the area of contiguous objects of white, check out the 'regionprops' function in the Image Processing Toolbox.
