2013-10-25 22:41:16 -0600	asked a question	Questions about the filter2D The parameter anchor of the function filter2D indicates the relative position of a filtered point within the kernel; But what is the detail of processing the value of the anchor? For example： The default value (-1,-1) means that the anchor is at the kernel center, but I think in this case the anchor.x and anchor.y are not equal to -1? What is the real value of the anchor? And how dose OpenCV process the value of the anchor?

2013-10-20 22:34:22 -0600	asked a question	Question about OpenCL versus GPU My question is: What is the difference between OpenCL and GPU? For example: In the OpenCV 2.4.4 documentation, there are two items of OpenCV API Reference, respectively gpu. GPU-accelerated Computer Vision and ocl. OpenCL-accelerated Computer Vision.
