Images
of the Russian Empire:Colorizing the Prokudin-Gorskii
photo
collection:
The program
was broken into three modules:
1.
To
obtain red, green and blue channel images from the original photo collection.
2.
Align
the images with respect to each other.
3.
Place
the three images over each other to produce the final image.
The code
for the program has been provided in 2 word document files.
The sum of
squared differences approach was used to obtain the alignment.
Here are
the results of the analysis:
Pictures on
the left side were obtained when images were overlaid without alignment.
Pictures on
the right side were obtained when images were overlaid with alignment.
It is clear
that aligned images look much better than the non aligned images.
Problems
with program:
1.
The edges
of picture are blurred and do not reveal the details in original picture.
2.
Mechanical
cropping in Adobe photoshop, followed by alignment gives rise to much better
Images. However, I was not able to develop an automatic
cropping program.
3.
Program
is unable to handle the large size images such as 00458, 01043. I tried to develop
a multiscale approach to alignment, however, the program is not fully complete
right now.
