Enable aruco module (recognize markers to detect camera pose) * Sat Jan 02 2021 Stefan Brüns <stefan.bruens@rwth-aachen.de> - update to 4.5.1, highlights below, for details check https://github.com/opencv/opencv/wiki/ChangeLog#version451 * Continued merging of GSoC 2020 results: + Develop OpenCV.js DNN modules for promising web use cases together with their tutorials + OpenCV.js: WASM SIMD optimization 2.0 + High Level API and Samples for Scene Text Detection and Recognition + SIFT: SIMD optimization of GaussianBlur 16U * DNN module: + Improved layers / activations / supported more models: - optimized: 1D convolution, 1D pool - fixed: Resize, ReduceMean, Gather with multiple outputs, importing of Faster RCNN ONNX model - added support: INT32 ONNX tensors + Intel® Inference Engine backend (OpenVINO): - added support for OpenVINO 2021.2 release - added preview support for HDDL + Fixes and optimizations in DNN CUDA backend (thanks to @YashasSamaga) * G-API Framework: + Introduced serialization for cv::RMat, including serialization for user-defined memory adapters + Introduced desync, a new Operation for in-graph asynchronous execution - to allow different parts of the graph run with a different latency + Introduced a notion of "in-graph metadata", now various media-related information can be accessed in graph directly (currently only limited to timestamps and frame IDs) + Introduced a new generic task-based executor, based on Threading Building Blocks (TBB) + Extended infer<>() API to accept a new cv::GFrame data structure to allow handling of various media formats without changes in the graph structure + Made copy() an intrinsic where real copy may not happen (optimized out) based on graph structure, extended it to support cv::GFrame + Various fixes, including addressig static analysis, documentation, and test issues * G-API Operations: + Introduced new operations morphologyEx, boundingRect, fitLine, kmeans, Background Subtractor, Kalman filter * G-API Intel® Inference Engine backend (OpenVINO): + Extended cv::gapi::ie::Params<> to import CNN networks (e.g. pre-compiled ones) instead of passing .XML and .BIN files; also enabled configuring Inference Engine plugins via this structure + Added a new overload to infer<>() to run inference over a single region of interest + Added support for cv::MediaFrame input data type (projected from cv::GFrame) and handling for NV12 input image format * G-API Python bindings: + Exposed G-API's Inference and Streaming APIs in the OpenCV Python bindings + Added initial Python support for cv::GArray data structure * Significant progress on RISC-V port. - Updated constraints, bump memory to 5 GB - Cleaned up spec file
