	#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
imgCorrected=colorCorrection(imgToConvert,mst,whitePixelMask)
