Function Documentation

decolor()

void cv::decolor	(	InputArray	src,
		OutputArray	grayscale,
		OutputArray	color_boost
	)

Transforms a color image to a grayscale image. It is a basic tool in digital printing, stylized black-and-white photograph rendering, and in many single channel image processing applications [102] .

Parameters

src	Input 8-bit 3-channel image.
grayscale	Output 8-bit 1-channel image.
color_boost	Output 8-bit 3-channel image.

This function is to be applied on color images.

inpaint()

void cv::inpaint	(	InputArray	src,
		InputArray	inpaintMask,
		OutputArray	dst,
		double	inpaintRadius,
		int	flags
	)

Restores the selected region in an image using the region neighborhood.

Parameters

src	Input 8-bit 1-channel or 3-channel image.
inpaintMask	Inpainting mask, 8-bit 1-channel image. Non-zero pixels indicate the area that needs to be inpainted.
dst	Output image with the same size and type as src .
inpaintRadius	Radius of a circular neighborhood of each point inpainted that is considered by the algorithm.
flags	Inpainting method that could be one of the following: INPAINT_NS Navier-Stokes based method [Navier01] INPAINT_TELEA Method by Alexandru Telea [152] .

The function reconstructs the selected image area from the pixel near the area boundary. The function may be used to remove dust and scratches from a scanned photo, or to remove undesirable objects from still images or video. See http://en.wikipedia.org/wiki/Inpainting for more details.
