I was playing with image thresholding and got some interesting results which I thought to share.
1. The original image:
2. Converted to black and white and image mode changes to greyscale. It now has just 256 levels of grey.
3. I then applied thresholding on the above image. It essentially converts the image to binary. There are pure black pixels and pure white pixels. Nothing in between (no grey).
Thresholding allows you to declare anything darker than a level as black and anything brighter than a level as white.
4. Another example:
I kind of like the out come. What do you think. Give it a try.
