LK Demo: OpenCV C++ to WebAssembly

https://nlabs-7652.github.io/OpenCV-CPP2WASM-LKDemo/

Overview

This project demonstrates the power of WebAssembly (WASM) by porting the OpenCV C++ LK (Lucas-Kanade) optical flow demo to run in web browsers. With the invaluable support of generative AI, we've achieved performance levels that rival native applications, all within a browser environment.

Key Features

Browser-based Performance: Experience desktop-like speed and responsiveness directly in your web browser. Cross-Platform Compatibility: One binary runs seamlessly across all major operating systems, eliminating the need for platform-specific ports. Mobile Support: Fully functional on tablets, including iPads, allowing point tracking with touch input. Direct C++ Implementation: Writing OpenCV code directly in C++ proved more straightforward than using opencv.js, offering greater control and familiarity for C++ developers.

Traditionally, porting applications to different operating systems like Windows or macOS required significant effort. This WebAssembly implementation demonstrates how a single binary can now run efficiently across all major platforms, streamlining development and distribution processes.

Click on any point in the demo to see real-time tracking in action. Whether you're on a desktop, laptop, or even an iPad, you'll be amazed at the smooth performance and accuracy of the point tracking.
