OpenCV:用标量划分Mat的最简单方法是什么 [英] OpenCV:Whats the easiest way to divide a Mat by a Scalar

问题描述

我认为标题中有很多内容，显然我可以遍历和划分.但是我认为这是一种内在的方式.我看到了cvConvertScale，但这不适用于类型cv::Mat.

I think it's pretty much in the title, obviously I can iterate through and divide. But I assume there is an inbuilt way. I saw cvConvertScale but this does not work with type cv::Mat.

推荐答案

我知道标量乘法的缩放操作:

I know the scaling operation for a multiplication by a scalar:

cv::Mat M;
float alpha;
cv::Mat Result = M * alpha;

让我们尝试一下:

cv::Mat Result = M / alpha;

或者:

float beta = 1.0f / alpha;
cv::Mat Result = M * beta;
