Removes haze and brings out the real colors in underwater photography. Apart from removing haze, it also enhances the colors of haze-less images and is so additive that you start using it on every underwater photo by default.

Function

CuviStatus cuvi::imageFiltering::underwaterFilter(const CuviImage& src,
                                                  CuviImage& dst,
                                                  CuviEnhamcementParams params = CuviEnhancementParams(),
                                                  const CuviStream& stream = CuviStream());

Parameters

Name Type Description
src const CuviImage& Input Image
dst CuviImage& Output Image
params CuviEnhacementParams bool autoColor, Cuvi32i filterStrength, Cuvi64f deGalreAmount.
stream const CuviStream& GPU stream ID for execution
