Description:
awblib 0.0.3
AWB-Lib
Implementation of a bunch of Automatic White-Balancing (AWBE algorithms), using JAX. Comparisons and experiments can be found in docs folder.
Implemented Algorithms
Gray World (GW), based on gray world assumption. See awblib.gw.
Colour Histogram Stretching (CHS). See awblib.chs.
Average Equalization and Threshold (AAET). See awblib.aaet.
Histogram Matching (AWB-HM), based on histogram matching. See awblib.hm.
Dynamic Histogram Matching (AWB-DHM), based on histogram matching and channel selection. See awblib.dhm.

Explanations about our implementation is here. This implementation largely reproduced the results.
Example Results
See docs for more.
Notes
Actually no paper has mentioned that if they are invariant to colour space or they depend on a specific colour space. As far as I know, most non-ML image processing algorithms require linear RGB; this processing is not done in this module yet.
