## Description

This project is a Java-based toolkit that integrates the OpenCV computer vision library into the Processing creative coding environment. It provides a programming interface designed to facilitate the inclusion of real-time image analysis and computer vision algorithms within interactive art installations and visual design projects.

The library distinguishes itself by wrapping low-level C++ routines into a managed environment, allowing users to perform complex visual tasks through a simplified interface. It supports high-performance operations by sharing raw pixel data between the host environment and the vision engine, and by enabling region-based computational scoping to focus processing resources on specific areas of a frame.

The toolkit covers a broad range of image processing capabilities, including feature detection, geometric analysis, and motion tracking. Users can perform tasks such as contour extraction, camera calibration, morphological operations, and statistical evaluation of visual data. The library is distributed as a library for the Processing environment, providing direct access to these functions for rapid prototyping and experimentation.
