The goal of this assignment is to take the digitized Prokudin-Gorskii glass plate images and, using image processing techniques, automatically produce a color image with as few visual artifacts as possible. I did the following:
| File Name | G Displacement | R Displacement |
|---|---|---|
| cathedral.jpg | (5, 2) | (12, 3) |
| monastery.jpg | (-3, 2) | (3, 2) |
| nativity.jpg | (3, 1) | (7, 0) |
| settlers.jpg | (7, 0) | (15, -1) |
| emir.tif | (45, 19) | (106, 35) |
| harvesters.tif | (59, 10) | (121, 7) |
| icon.tif | (40, 16) | (89, 22) |
| lady.tif | (57, -6) | (103, -13) |
| self_portrait.tif | (76, 15) | (171, 23) |
| three_generations.tif | (52, 5) | (110, 7) |
| train.tif | (40, -3) | (91, 19) |
| turkmen.tif | (56, 11) | (109, 15) |
| village.tif | (61, -1) | (137, 19) |
Change to compare SSD difference of the canny edge version of the image at every image pyramid level

Pixelwise trasform each channel. The transformation stretch each channel to it's full range ignoring the pure black/white and intensities appears less than a threshold.
These are the Blue channel histograms of emir.tif before and after the auto process.
