[英]Accessing Whole Channel in a multi channel array in opencv
I'm trying to access a whole channel in a 3 channel image in opencv (to replace a channel with a whole matrix, see below). 我正在尝试在opencv的3通道图像中访问整个通道(以整个矩阵替换通道,请参见下文)。 Is it possible to do so without looping through the individual pixel values?
是否可以这样做而不循环遍历各个像素值?
Mat RGB(320, 480, CV_8UC3)
Mat R(320, 480, CV_8UC1)
Mat G(320, 480, CV_8UC1)
Mat B(320, 480, CV_8UC1)
// First channel of RGB = R
// second channel of RGB = G
// third channel fo RGB = B
