◆ bitwise_and() [1/2]

GMat cv::gapi::bitwise_and	(	const GMat &	src1,
		const GMat &	src2
	)

#include <opencv2/gapi/core.hpp>

computes bitwise conjunction of the two matrixes (src1 & src2) Calculates the per-element bit-wise logical conjunction of two matrices of the same size.

In case of floating-point matrices, their machine-specific bit representations (usually IEEE754-compliant) are used for the operation. In case of multi-channel matrices, each channel is processed independently. Output matrix must have the same size and depth as the input matrices.

Supported matrix data types are CV_8UC1, CV_8UC3, CV_16UC1, CV_16SC1, CV_32FC1.

Note: Function textual ID is "org.opencv.core.pixelwise.bitwise_and"

Parameters

src1	first input matrix.
src2	second input matrix.
