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.

Thanks for helping. I got it.
how could u solve it, sir ? if u don't mind for sharing it
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
