Is there a real world need for you to do this, or is it just a homework exercise? How did you ever come to have pictures of some torn up photograph at oddball angles? If you work in forensics and need to reconstruct a photo that the suspect tore up, this can be done very easily with Photoshop and manual interaction. There is no need to write some complicated program when you don't have to.

The JPEG image format cannot store non-rectangular images. MATLAB cannot store non-rectangular arrays.
What you can do in some cases is to read in rectangular images, and found the visual boundary of them, and construct a "mask" to select only the visual object. See for example http://www.mathworks.com/matlabcentral/answers/76961
