Worked on enhancing the stability of JavaScript bindings in the opencv/opencv repository, focusing on factory functions that return cv::Ptr<T> where T is a namespaced class. Addressed a bug in the binding generator by updating the embindgen.py logic to emit fully-qualified class names for such pointers, ensuring valid C++ template arguments in the generated code. This approach prevents runtime binding errors and improves cross-module interoperability for JavaScript users. The solution was validated through targeted builds and generator runs, leveraging C++, Python, and OpenCV expertise to deliver more robust and maintainable JS bindings without modifying generated files directly.
