Makes sense of hazy images. Note this function is ideal for extreme blizzard and very low visibility. For small hazes, we prefer using Function:adjust.

Function

CuviStatus cuvi::colorOperations::dehaze(const CuviImage& src,
                                         CuviImage& dst,
                                         int max0,
                                         int max1,
                                         int max2,
                                         const CuviStream& stream = CuviStream());

Example

CuviImage input("D:/blizzard.jpg", CUVI_LOAD_IMAGE_COLOR_KEEP_DEPTH), output;
 
//Perform dehaze. For most practical purposes the max values will be container's max. 
cuvi::colorOperations::dehaze(input, output, 255, 255, 255);
 
//Save Output to file
cuvi::io::saveImage(output, "D:/sense.jpg");
