I don't have the complete list.But I will check the source code in ...\opencv\sources\modules if I feel some functions costing too much time. The functions updated to T-API contain opencl kernels in their source codes. |
| 2015-06-13 04:13:52 -0600 | commented answer | OpenCV 3.0 ,the performance of UMat Hi, I meet the same problem. I tested UMat with cv::ocl::goodFeaturesToTrack in three conditions: UMat/setUseOpenCL(true), UMat/setUseOpenCL(false) and only using cv::Mat. In debug mode, the first situation runs much quicker; but in release mode, they almost have the same runtime. I checked the source code of cv::ocl::goodFeaturesToTrack and it did have a OpenCL kernel. So it should have been updated with T-API. BTY, I also test the some function with the OpenCV2.4.11's ocl module. It runs a little faster than that with UMat. I'am considering turning back to OpenCV2.4.11 :( |
