OpenCvSharp and .NET Guides

These guides cover the parts of using OpenCV that are specific to OpenCvSharp, C#, and .NET applications. They focus on managed and native ownership, API shapes, memory access, framework integration, and resource lifetimes rather than repeating OpenCV's algorithm documentation.

Core data and ownership

• Mat Basics introduces the managed wrapper around cv::Mat, including views, clones, types, and dimensions.
• Resource Management explains deterministic disposal and ownership transfer for native resources.
• InputArray, OutputArray, and In-place Processing explains temporary proxies, destination arguments, and safe in-place operations.
• Copies, Native Memory, and Performance distinguishes headers, views, clones, managed copies, and reusable buffers.
• Pixel Access compares indexed, row-based, span-based, and pointer-based access.

Application integration

• Image Encoding and Conversion converts between Mat, encoded byte buffers, and framework bitmap types.
• File Storage reads and writes OpenCV documents and integrates FileNode with System.Text.Json.
• ASP.NET Core Image Uploads and Streams processes bounded uploads, streams, and HTTP responses.
• Display Images in .NET Applications integrates WPF, Windows Forms, and Avalonia controls.
• Video I/O covers capture loops, writers, backends, and resource ownership.

OpenCV algorithms

Continue to the OpenCV Examples for C# examples of image-processing, transformation, contour, histogram, and feature APIs. Those pages link to the official OpenCV documentation for algorithm theory and parameter definitions.
