Project 1 - Images of the Russian Empire
Sonja Duric

Algorithm and Comments
My algorithm for colorizing the Prokudin-Gorskii collection of three-channel images first crops the unnecessary white borders found in some images as well as the damaged edges of the glass plates before using Normalized Cross-Correlation to find the alignment vectors. This implementation of NCC uses a pyramid scheme to handle high resolution images. Once the alignment vectors are found, the three channels are put together to create color images, as seen below.
I found that the damaged edges created issues for the NCC algorithm and were unsightly in the finished product, so cropping before alignment solved both of these issues.

Flowers - 00946u.tif
Sailors - 00955u.tif
- There is one sailor in this image who appeared blurry in the red-channel image. I believe this is why he is un-aligned while his compatriots all appear life-like.
