Architecture

Overview​

The OpenCV crate provides Rust bindings for OpenCV (Open Source Computer Vision Library), enabling computer vision, machine learning, and image processing capabilities in Rust applications.

Core Components​

Binding Layer​

  • Native Bindings: Direct FFI bindings to OpenCV C++ libraries

  • Safe Wrappers: Rust-safe abstractions over raw OpenCV functions

  • Memory Management: Automatic resource cleanup and lifetime management
