colorCorrection {CRImage} | R Documentation

## Color transfer between images.

### Description

The colors of one image are adapted to the colors of a target image.

### Usage

    colorCorrection(imgO, meanStdTarget,whiteMask = c())

### Arguments

`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.

### Details

Mean and standard deviation of the target image can be calculated using the function calculateMeanStdTarget.

### Value

The image with adapted colors.

### Examples

    #read the target image
    	f1= system.file("extdata", "exImg2.jpg", package="CRImage")
    	targetImage=readImage(f1)
    	#read the image whose color values should be adapted
    	f2= system.file("extdata", "exImg3.jpg", package="CRImage")
    	imgToConvert=readImage(f2)
    	#calculate mean and standard deviation of target color channels
    	mst=calculateMeanStdTarget(targetImage)
    	# create a white pixel mask
    	whitePixelMask=imgToConvert[,,1]>0.85 & imgToConvert[,,2]>0.85 & imgToConvert[,,3]>0.85
    	#adapt color channels of image
