@ -47,16 +44,16 @@ Spring update for OpenCV 4.x has been released.
- Introduced a new Python backend - now G-API can run custom kernels written in Python as part of the pipeline: [#19351](https://github.com/opencv/opencv/pull/19351);
- Extended Inference support in the G-API Python bindings: [#19318](https://github.com/opencv/opencv/pull/19318);
- Added more graph data types support in the G-API Python bindings: [#19319](https://github.com/opencv/opencv/pull/19319);
- Inference support:
- Introduced dynamic input / CNN reshape functionality in the OpenVINO inference backend [#18240](https://github.com/opencv/opencv/pull/18240);
- Introduced asynchronous execution support in the OpenVINO inference backend, now inference can run in multiple requests in parallel to increase stream density/throughput: [#19487](https://github.com/opencv/opencv/pull/19487), [#19425](https://github.com/opencv/opencv/pull/19425);
- Extended supported data types with INT64/INT32 in ONNX inference backend and with INT32 in the OpenVINO inference backend [#19792](https://github.com/opencv/opencv/pull/19792);
- Introduced `cv::GFrame` / `cv::MediaFrame` and constant support in the ONNX backend: [#19070](https://github.com/opencv/opencv/pull/19205);
- Media support:
- Introduced `cv::GFrame` / `cv::MediaFrame` support in the drawing/rendering interface: [#19516](https://github.com/opencv/opencv/pull/19516);
- Introduced multi-stream input support in Streaming mode and frame synchronization policies to support cases like Stereo: [#19731](https://github.com/opencv/opencv/pull/19731);
- Added `Y` and `UV` operations to access NV12 data of `cv::GFrame` at the graph level; conversions are done on-the-fly if the media format is different: [#19325](https://github.com/opencv/opencv/pull/19325);
