more tests and results

As planned, I ran some denoising functions on the images (NOTE : conversion to float was needed).
After this, I compared the outputs from tesserat on the 5 images side by side. They denoising filters I tried are :

1. Bilateral filters: This seems to give improved results.
2. Total variation filter using split-Bregman : No improvements.
3. Chambolle : Very little Improvements.

The sample outputs can be seen here.

Just as a reminder, the original image looked as

Next Up, some playing with the resolution before moving on work with characters individually from next week. So Long.

As a side note, I also tried the same procedure with another test image using a separate font, but as expected, it did not perform well.
