CodeBrix.VideoProcessing.OpenCV5

A fully managed .NET binding for OpenCV 5, derived from the OpenCvSharp5 project, providing image processing, video capture/analysis, camera calibration, object detection, machine learning, and the OpenCV contrib extra modules to .NET applications on Windows, Linux, and macOS (x64 and ARM64, plus RISC-V 64 on Linux). CodeBrix.VideoProcessing.OpenCV5 has no managed dependencies other than .NET, and is provided as a .NET 10 library and associated CodeBrix.VideoProcessing.OpenCV5.ApacheLicenseForever NuGet package, plus per-platform native binding packages (see below).

CodeBrix.VideoProcessing.OpenCV5 supports applications and assemblies that target Microsoft .NET version 10.0 and later. Microsoft .NET version 10.0 is a Long-Term Supported (LTS) version of .NET, and was released on Nov 11, 2025; and will be actively supported by Microsoft until Nov 14, 2028. Please update your C#/.NET code and projects to the latest LTS version of Microsoft .NET.

CodeBrix.VideoProcessing.OpenCV5 supports:

• The OpenCV 5 core, imgproc, imgcodecs, videoio, video, calib3d, features, flann, dnn, ml, objdetect, photo, stitching, and highgui modules via the Cv2 static class and the Mat family of types
• The OpenCV contrib extra modules: aruco, barcode, face, img_hash, line_descriptor, quality, saliency, shape, text, tracking, wechat_qrcode, xfeatures2d, ximgproc, xphoto, dnn_superres, and more
• Windows x64 and ARM64, Linux x64, ARM64, and RISC-V 64, and macOS x64 and Apple Silicon via per-platform native runtime packages
• WPF interop (Mat ↔ BitmapSource / WriteableBitmap) via the CodeBrix.VideoProcessing.OpenCV5.Wpf.ApacheLicenseForever package
• Built-in Roslyn analyzers that catch common Mat usage mistakes (undisposed Row/Col results, Mat property access in loop conditions) at compile time

The package family

Applications reference the core package plus the native runtime package(s) matching their target platform(s).

The Linux native libraries are portable, statically-linked builds (the manylinux model): one binary per architecture that runs on effectively any modern glibc distribution — Debian, Ubuntu, Raspberry Pi OS, RHEL-family, and more (glibc 2.28+ for x64/ARM64; glibc 2.39+ for RISC-V 64).

Sample Code

Reading, processing, and saving an image

using CodeBrix.VideoProcessing.OpenCV5;

using var src = Cv2.ImRead("input.jpg", ImreadModes.Grayscale);
using var dst = new Mat();

Cv2.Canny(src, dst, 50, 200);
Cv2.ImWrite("edges.png", dst);

Capturing frames from a video file

using CodeBrix.VideoProcessing.OpenCV5;

using var capture = new VideoCapture("movie.mp4");
using var frame = new Mat();

while (capture.Read(frame))
{
    // process each frame ...
}
