G-API (Graph API) is an OpenCV module that, instead of executing an image processing pipeline immediately, first defines it as a computation graph and then compiles and runs it. Because the whole graph is known, optimizations such as reducing intermediate buffers and fusing operations are possible, and the same graph can be sent to different execution environments such as CPU, OpenCL, and the OpenVINO inference backend. It is designed for workloads that repeat the same processing for every frame, such as video streams.
