OpenCV:GPU is a page about using GPU acceleration in OpenCV. OpenCV provides the NVIDIA CUDA-based cv::cuda module (formerly the gpu module) and the OpenCL-based Transparent API (cv::UMat), which let operations such as image filtering, feature extraction, stereo matching, and object detection run on the GPU. Because transferring memory between host and device has a cost, the gain is small for small images or single operations.
