OpenCV 4.11.0 💾

An open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. Being a BSD-licensed product, OpenCV makes it easy for businesses to utilize and modify the code.

major feature: New Year update for OpenCV 4.x has been released. Generic: Internal C API cleanup and back-ports for 5.x. RISC-V/AArch64: disable CPU features detection #25901 Support C++20 standard #26590 algoHint parameter for some functions to allow potentially faster, but not bit-exact implementation Core Module: Added int64 data type support for FileStorage #26434 Fixed invalid attribute value handling in FileStorage #25955. Extended LUT for FP16 support #25787. Fixed stdDev tail filling with zeros with HAL in meanStdDev #25789. Set and check allocator pointer for all cv::Mat instances #25979 Improved accuracy of Rect::contains #26022 Fixed result offset in minMaxIdx with HAL in some cases #26080 Replaced C++ operators with wrapper functions on universal intrinsics backends #26109 Extended cv::TickMeter #26212 Rewrote OpenCL-OpenGL-interop device discovery routine without extensions and with Apple support #26281 Marked cv::Mat(Mat ) as noexcept #25899 Multiple Eigen library interop improvements #25751. Calib3d module: Multiple chessboard detector improvements #25427, #25807, #25991, #26014 Enabled checkerboard detection with a central / corner marker on a black tile #25808 Fixed Rodrigues CV_32F and CV_64F type mismatch in projectPoints #25824 Added fisheye::distort with non-identity projection matrix #25943 SQPnP solver updates #26219 Fixed vector access in USAC #26530 Imgproc Module: Added a new function that approximates the polygon bounding a convex hull with a certain number of sides #25607 Added Weighted Hough Transform #21407 Fixed bug in contours approximation #25672 Fixed bug in divSpectrums #25738 Fixed result buffer overflow in intersectConvexConvex_ for non-convex input #25725. Added flag to GaussianBlur for faster but not b

Connected Component Labeling for GPGPU 1.1

Connected Component Labeling (CCL) is a well known technique for assigning a unique label to each of connected components in a given binary image. In this project, libraries that implement a parallel CCL algorithm that is suitable for execution on GPGPU are provided. In the archive, an implementation in OpenCL and C that is usable in combination with OpenCV library, a single-threaded vectorized CPU implementation that utilizes AVX2 instructions, and a Java implementation that is for helping unde

Diffimg 2.2.0

DiffImg computes pixel discrepancies between two image files and displays them as color mask or as yellow/red overlay. It also provides a dual panel display, can compute the mean error, RMS and min/max values, shows an error histogram, or display a slideshow for image directories. This allows for compression level comparisons, or optimizing raytracing parameters.
