OpenCV 6 - 图像对比度和亮度的调节

对比度和亮度的调节理论

代码示例

	Mat src, dst;
	src = imread("./1.png");
	if (!src.data)	//判断图片是否加载成功!
	{
   
		std::cout << "打开图片失败!" << std::endl;
		return -1;
	}
	//将src变成灰度图像(单通道)
	//cvtColor(src, src, CV_RGB2GRAY);
	imshow("src image", src);

	int height = src.rows;
	int width  = src.cols;

	dst = Mat::zeros(src.size(),src.type());

	float alpha = 1.5f;
	int beta  = 40;
	for (int i = 0; i < height; i++)<
