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.

- 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.
