awb-lib's Issues

Artefacts in CHS realization

You can see a lot of color artefacts in the AWB-Lib example of CHS and modCHS (https://github.com/JoeyTeng/AWB-Lib/blob/master/docs/assets/report.png). I mean some pixel have totally different color in comparison with as it should be. And there is a remark about it "The implementation largely reproduced the results", but in the corresponding article "Fast automatic white balancing method by color histogram stretching" there are no such artefacts. I think there is something wrong with the realization of CHS method in AWB-Lib
