How to split image into small blocks 4x4, 8x8 ..., process on them and then join all the blocks together again in python?
There is a similar issue being treated in StackOverflow,
https://stackoverflow.com/questions/22685274/divide-an-image-into-5x5-blocks-in-python-and-compute-histogram-for-each-block
In there they use a histogram on each subframe, you can apply your own process. Afterwards, reversing the process you can create the new image.
Hope it's useful!
use normal data slicing or normal row-column operation in python. Or you can do by numpy or panda...
Here is a quick solution that can generate from 4x4 to n*m blocks. Add a check while loading image file to make sure that your image is properly padded.
