- update to 4.8.1 * WebP security update for CVE-2023-4863 * Depthwise convolution 5x5 performance regression fix - update to 4.8.0, highlights below, for details check https://github.com/opencv/opencv/wiki/ChangeLog#version480 Highlights of this release: * DNN module patches: + TFLite models support, including int8 quantized models. + Enabled DNN module build without Protobuf dependency. + Improved layers => supported more models: - ONNX: Layer normalization, GELU and QLinearSoftmax. - Fixes in CANN backend: * support ONNX Split, Slice, Clip (Relu6) and Conv with auto_pad. * support ONNX Sub, PRelu, ConvTranspose. - Reduce Refactor for robustness and potential follow-up improvements. - Fixes for Segment Anything Model by Meta. - Fixes in nary element wise layer about broadcast: * Fixes in CPU. * and Fixes in CUDA backend. - Further increased DNN speed on ARM and X86 by improving convolution, covering 1D and 3D cases, supporting convolution+element-wise op fusion. - Added full FP16 computation branch on ARMv8 platform, 1.5x faster than FP32 (FP16 Winograd is still pending). - Vulkan backend refactor for better performance and robustness. It runs 4X faster than before. - Added API blobFromImageParam to build network inputs with pre-processings. - Modern OpenVINO support. * G-API module: + Intel® OpenVINO™ inference backend: - Streamlined preprocessing in OpenVINO Inference Engine (ie) API 1.0 backend. Note: this backend will be deprecated after OpenVINO removes the API 1.0 support in its subsequent releases. - Aligned OpenVINO IE API 1.0 backend with the latest OpenVINO 2023.0 (as some features were removed there). - Introduced a brand new OpenVINO API 2.0 backend. - Implemented the required inference operations for the OpenVINO API 2.0 backend. + Python bindings: - Exposed varions normalization options for ONNX RT backend in Python bindings. - Exposed Fluid kernels and kernel package manipulation functions (combine()) in Python. - Fixed issues in Stateful Python kernel state handling; also fixed various issues in Python tests. - Fixed issue with opaque kernel output information handling which broke Python custom kernels. + Samples: - Introduced a new Segmentation demo with desync() to enable slow-running networks in the real-time. - Updated stats calculation in the G-API-based pipeline modelling tool. + Other changes and fixes: - Fixed tolerance in Fluid resize tests to avoid issues on ARM. - Fluid backend: extended Merge3 kernel with more supported data types. - Fixed standalone mode compilation issues. * Objdetect module: + FaceDetectorYN upgrade for better performance, accuracy and facial landmarks support. + New QR code detection algorithm based on ArUco code. + Bar code detector and decoder moved from Contrib to main repository. + Introduced common API for all graphical codes like bar codes and QR codes. + Added flag for legacy pre-4.6.0 ChAruco boards support. + Multiple bug fixes and improvements in QR code detection and decoding pipelines. + Multiple bug fixes and improvements in ArUco based pipelines. * Calibration module: + USAC framework improvements. + Fixed stddev estimation in camera calibration pipelines. + Fixed incorrect pixel grid generation in icvGetRectangles that improves accuracy of getOptimalNewCameraMatrix, stereoRectify and some other calibration functions. Charuco board support in patterns generator, interactive calibration tool and calibration samples. * Image processing module: + Various fixes in line segments detector. + Fixed even input dimensions for INTER_NEAREST_EXACT in resize. + Optimise local cost computation in IntelligentScissorsMB::buildMap. + Keep inliers for linear remap with BORDER_TRANSPARENT + Fix distransform to work with large images. * Features2d module: + SIFT accuracy improvements. * Core module: + Added REDUCE_SUM2 option to cv::reduce. + Introduced cv::hasNonZero function. + Update IPP binaries update to version 20230330. + Improved RISC-V RVV vector extensions support. - Support RVV v0.11 intrinsics available in LLVM 16 and GCC 13 - Support build with T-Head RISC-V toolchain (RVV 0.7.1 and 1.0) + Several OpenCL vendor and version handling improvements. * Multimedia: + Added AVIF support through libavif. + Orbbec Femto Mega cameras support. + HEVC/H265 support in VideoWriter with MS Media Foundation backend. + Fixed FPS computation on some videos for FFmpeg backend. + Added support for VideoCapture CAP_PROP_AUTO_WB and CV_CAP_PROP_WHITE_BALANCE_BLUE_U for DShow backend. + Fixes OBS Virtual Camera capture. + CV_32S encoding support with tiff. * Python Bindings: + Python typing stubs. + Fix reference counting errors in registerNewType. + Fixed ChAruco and diamond boards detector bindings. + Added bindings to allow GpuMat and Stream objects to be initialized from memory initialized in other libraries + np.float16 support. + Python bindings for RotatedRect, CV_MAKETYPE, CV_8UC(n). * JavaScript bindings: + Added possibility for disabling inlining wasm in opencv.js + Extended JS bindings for Aruco, Charuco, QR codes and bar codes. * Other: + Several critical issue fixes in wechat_qrcode module (opencv_contrib) OBS-URL: https://build.opensuse.org/request/show/1114642 OBS-URL: https://build.opensuse.org/package/show/science/opencv?expand=0&rev=36
