"T-API" means "Transparent API".
I think that the following document is useful to understand "Transparent API". http://code.opencv.org/attachments/1591/OpenCV3_0_CVPR_2014.pptx
To complement @dandelion1124's answer, here is the relevant slide 19:
GPU acceleration: Transparent API
- same code can run on CPU or GPU – no specialized
cv::Canny,ocl::Canny, etc; no recompilation is needed- minimal or no changes in the existing code
- CPU-only processing – no changes required
- includes the following key components:
- new data structure UMat
- simple and robust mechanism for async processing
- open to extensions: convenient OpenCL wrappers for accelerating user algorithms
Please let me explain further. If you call ocl::setUseOpenCL() explicitly, you can select the behavior of UMat. This function's argument is boolean value. If you use this function, you need to include <opencv2/core/ocl.hpp>.
