Function Documentation

cvtColor() [1/2]

void cv::cann::cvtColor	(	const AscendMat &	src,
		AscendMat &	dst,
		int	code,
		int	dstCn = 0,
		AscendStream &	stream = AscendStream::Null() )

#include <opencv2/cann_interface.hpp>

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

cvtColor() [2/2]

void cv::cann::cvtColor	(	const InputArray	src,
		OutputArray	dst,
		int	code,
		int	dstCn = 0,
		AscendStream &	stream = AscendStream::Null() )

#include <opencv2/cann_interface.hpp>

Converts an image from one color space to another.

Parameters

src	Source image with CV_8U , CV_16U , or CV_32F depth and 1, 3, or 4 channels.
dst	Destination image.
code	Color space conversion code. For details, see cv::ColorConversionCodes .
dstCn	Number of channels in the destination image. If the parameter is 0, the number of the channels is derived automatically from src and the code .
stream	AscendStream for the asynchronous version.

Note

The supported conversion types are as follows: { CV_BGR2BGRA, CV_BGRA2BGR, CV_BGR2RGBA, CV_RGBA2BGR, CV_BGR2RGB, CV_BGRA2RGBA, CV_BGR2GRAY, CV_RGB2GRAY, CV_GRAY2BGR, CV_GRAY2BGRA, CV_BGRA2GRAY, CV_RGBA2GRAY, CV_BGR2XYZ, CV_RGB2XYZ, CV_XYZ2BGR, CV_XYZ2RGB, CV_BGR2YCrCb, CV_RGB2YCrCb, CV_YCrCb2BGR, CV_YCrCb2RGB, CV_BGR2YUV, CV_RGB2YUV, CV_YUV2BGR, CV_YUV2RGB }
