Colorizing the Prokudin-Gorskii Photo Collection
Background
The goal of this project is to create a color-version of the Prokudin-Gorskii
photos which has three channels, RGB, of the same photo using Gaussain pyramid
method for large high resolution images and sum of the square differences.
Conclusion/Discussion
My Program worked for all the low resolution images. But it did not work for all the
high resolution images. I think this was because since the images were too big, when
the correlation offset is doubled when going back to the original image (2x), this didn't actually have
the correct correlation offset. All the low reslution, high resolution, and a user chosen image can be seen below.
Low-res Images
shift G (1, -7), shift B (0, -12)
shift G (1, -4), shift B (0, -10)
shift G (0, 2), shift B (-1, 4)
shift G (0, -9), shift B (0, -9)
shift G (2, -7), shift B (5, -13)
shift G (-1, -5), shift B (-2, -11)
shift G (0, -8), shift B (-3, -14)
shift G (0, -7), shift B (-2, -13)
shift G (-9, 1), shift B (-15, -1)
shift G (1, -8), shift B (1, -14)
shift G (0, -10), shift B (0, -15)
shift G (-1, -6), shift B (-3, -11)
Hi-res Images
shift G (-24, -44), shift B (0, -60)
shift G (19, -5), shift B (43, -61)
shift G (3, -61), shift B (7, -61)
shift G (-13, -49), shift B (29, -57)
shift G (7, -57), shift B (15, -61)
shift G (-9, -61), shift B (-13, -61)
shift G (-21, -61), shift B (-25, -61)
User chosen Image
The user chosen image was actually interesting because it produced three color versions of the image instead of one.
