colorCorrection {CRImage} | R Documentation |
The colors of one image are adapted to the colors of a target image.
colorCorrection(imgO, meanStdTarget,whiteMask = c())
imgO |
The image who's colors should be adapted |
meanStdTarget |
Array with mean and standard deviation of the target image. |
whiteMask |
Boolean mask of white pixel in the image. These pixels are excluded from color correction. |
Mean and standard deviation of the target image can be calculated using the function calculateMeanStdTarget.
The image with adapted colors.
