Auto-Thresholding Methods (pure AS3)

Auto-Thresholding | Pure AS3

I’m currently all in Image Processing stuff! ;) You will agree with me that it is very interesting field to discover. We all saw Mario Klingemann’s post on automated threshold. His post already covered some useful methods but I’ve small addition to it:

1. Triangle Algorithm by Zack GW
2. Huang’s fuzzy thresholding method that is using Shannon’s entropy function

I thought they should be covered too as far as they produced very nice results especially for pattern detection.
This methods is pure AS3 coded. You can see that triangle method is a lot faster but Huang’s more accurate.

Next time I’ll talk about several Adaptive Thresholding methods implemented in Pixel Bender and also will post all sources on thresholding experiments including this one.
