Maybe not PCA, but a simpler linear model (a la CfL/LM) built from running stats, or neighbourhood. But yes, for Bayer and/or RGB and/or higher-chroma-sampling images, that sounds like a great idea. -- Christophe > _______________________________________________ ffmpeg-devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
