I have to do:
Initial decorrelation on RGB color components of each image / frame to have an efficient codification ( without duplication ) of the input data through analysis of the principal components (PCA ), adapted to local image statistics ( rbgDecorr in AWS.m of Matlab ) .We obtain the three components Z1 , Z2 and Z3 in the block figure Whitening Color . This operation is performed by colorDecorrelation( ) function .
I have yet done colorDecorrelation function and it works. But in main I don t know how to do all is written before and in the image. P.D. All must done in a MAT object
