Project 1 - Colorizing the Prokudin-Gorshkii photo collection

Description of Project

I used the Sum of Square Differences technique and circshift to align these images. I also aligned on the Green image - when I implemented the basic mode, the green produced better results. I found that all of these images turned out ok, with the exception of one. I have shown two versions of that one - one with image pyramids, one without. In addition, I didn't apply ssd to the whole image matrix. I only used the center most portion (1/4 of the image in the center). The image pyramidss were made with 4 images (including the fullsize).
