Although I have been programming for a while (~10 years since I first learn programming), I have not yet made any (significant) contributions to existing works. I have done many projects, but all of them are either myself only or me and another designer. This changed last October, when I start contributing to AviSynth+, a modern fork of original AviSynth project, seriously. For a note, AviSynth is a script-based, non-linear video editing program/library.

In my most recent Introduction to Computer Programming (aka CS101), the instructor decided to shows us very simple image processing: blurring and secret image hiding. There are quite a number of things he did not mention because they are too complicated, but I think someone might be interested so I decided to write it here.

I am not talking about how to load image or save image, you can easily find documentation online for your favourite language. Our professors talk about two algorithm in class: blurring and secret image hiding. I am going to cover only these two here.
