I = imread('cameraman.tif');
[I2, rect] = imcrop(I);
imshow(I2) ;
imwrite(I2,'Example.jpg')
Extract the part you want, say it is I2. Using imwrite you can write the mage you want.

The code I gave was this.
for k = 1 : size(BB, 1)
face = imcrop(img, BB(k, :));
figure;
% subplot(6, 6, k);
imshow(face);
drawnow;
thisFileName = sprintf('Face #%d.png', k);
fullFileName = fullfile(pwd, thisFileName);
imwrite(face, fullFileName);
end
You'll see it if you click the "Show older comments" link above.

Hello there. I want to get an object in the rgb picture, how can I do that. For example, there is a banana on the table and the background is black. How can I get only the banana picture from the picture. ı dont want to take by boundingbox. I must take with border coordinates because ı need just object.There should be no background in the picture I'm waiting for your help.pleaseeee

The background is a problem because I will take only the banana object in this picture and operate on it.

You cannot do that. The closest you can get is

with all of the boundary taken out. But you cannot get rid of the black part to the lower left, for example, because doing so would involve creating a "ragged" array where those black pixels literally do not exist even though pixels above or to their right exist.
