OpenCV 4.3.0 在 GPU 上计算积分图像>

Question

So I found the function to compute the GPU integral image here .

The functions I need are gpu::integral and gpu::sqrIntegral (if there's a function that compute both the integral image and squared integral image at the same time, it would be best).

However, in OpenCV 4.3.0, I cannot find these functions at all. I can only find the CPU version here . Where have the GPU version been moved to?

Answer 1

I found cv::gpu::integral in the namespace cv::cuda . There're many changed between OpenCV 2 and 4. I hope that you also refer to UMat which accelerates using OpenCL and easy to learn.
