Function Documentation

applyColorMap() [1/2]

void cv::applyColorMap	(	InputArray	src,
		OutputArray	dst,
		int	colormap
	)

Python:
	dst	=	cv.applyColorMap(	src, colormap[, dst]	)
	dst	=	cv.applyColorMap(	src, userColor[, dst]	)

Applies a GNU Octave/MATLAB equivalent colormap on a given image.

Parameters

src	The source image, grayscale or colored of type CV_8UC1 or CV_8UC3.
dst	The result is the colormapped source image. Note: Mat::create is called on dst.
colormap	The colormap to apply, see ColormapTypes

Examples

samples/cpp/falsecolor.cpp.

applyColorMap() [2/2]

void cv::applyColorMap	(	InputArray	src,
		OutputArray	dst,
		InputArray	userColor
	)

Python:
	dst	=	cv.applyColorMap(	src, colormap[, dst]	)
	dst	=	cv.applyColorMap(	src, userColor[, dst]	)

Applies a user colormap on a given image.

Parameters

src	The source image, grayscale or colored of type CV_8UC1 or CV_8UC3.
dst	The result is the colormapped source image. Note: Mat::create is called on dst.
userColor	The colormap to apply of type CV_8UC1 or CV_8UC3 and size 256
