Hi, I'd like to better the issue #71. I finally find some English material (Lisa J. Croner, Thomas Wachtler (auth.), Christian J. van den Branden Lambrecht (eds.)-Vision Models and Applications to Image and Video Processing-Springer US (2001)) describes this phenomenon. From that book, I found it should be explained with experiment as well, but sadly, there is no detail process. Also, here is a picture in that book, although I think it may be illegal used in this free project, but I'd like post here and if we find an alternative of it, we can attach it to the article. 2018-08-12-145553_1920x1080_scrot

Maybe we can add this as a more in depth explanation but the simplistic still might help

I copied the explanation back into the file. And.. it might bother you to reformat a bit.

Sorry for the type errors, I have fixed them and removed some words that seems to be unnecessary.
