cv::convertScaleAbs() is used to implement the following operations for each element in the entire image array:
This operation can realize the fast calculation of image enhancement and other related operations. The specific usage is as follows:
void cv::convertScaleAbs(
cv::InputArray src, // input array
cv::OutputArray dst, // output array
double alpha = 1.0, // multiplier factor
double beta = 0.0 // offset
);
The following uses a specific example to demonstrate the magical use of this function:
cv::Mat src = cv::imread("img0.jpg", -1);
cv::Mat dst;
cv::convertScaleAbs(src, dst, 1.5, 10);
cv::imshow("src", src);
cv::imshow("dst", dst);
cv::waitKey(0);
return;
The results are as follows:
