Use imrect to select a rectangle in your image, and get its position, then create a new image and save it

im=imread('pout.tif');
imshow(im);
h=imrect(gca);
pos=wait(h);
im2=imcrop(im,pos);
imwrite(im2,'figurepart.bmp')
Automatically saves the crop you made. ofcourse you'll have im to the desired image.
