MATLAB Image cropper for multiple images?

I have 19 images, and I would like to be able to crop them the same way, cropping the same area on each image. But I need to look at the first image and determine which part of the image I want to crop. Then I would like to apply this crop to all other images. My idea is that I could save the four corner points from the first crop, and then repeat all the other 18 images, using 4 points to set the crop correctly. Does this sound like a good approach? Or does anyone know of a Matlab program that does this already ?, I'm already looking.

Use IMCROP from the Image Processing Toolbox.

For the first image, execute it interactively and save the selected coordinates of the rectangle as a variable ( rect):

[im_cropped rect] = imcrop(im);

Then for other images, these coordinates are applied:

im_cropped = imcrop(im, rect);
