imconvert

imconvert is an image color space conversion library. Apart from the typical color conversions such as, e.g., RGB to Grey, it allows to perform color decorrelation (PCA, ZCA, ICA), color space normalization (01, Median Absolute Deviation, and TanH), and color space weighting. Furthermore, it allows to train own decorrelated color spaces based on given image sets.

Visual Saliency Detection". In Proceedings of the 20th International 
Conference on Image Processing (ICIP), 2015.
