In June 2026, delivered a critical fix to the OpenCV.js binding generator for factory functions returning cv::Ptr<T> when T is a namespaced class in the ximgproc module (EdgeDrawing). The change centralizes the qualification logic for Ptr return-types, ensuring bindings reference the fully qualified C++ type (e.g., Ptr<cv::ximgproc::EdgeDrawing>) and resolving a long-standing EdgeDrawing binding issue. This eliminates a class of runtime binding errors for OpenCV.js users and improves cross-module compatibility with opencv_contrib/ximgproc. The work improves stability for web-based image processing workflows and reduces maintenance burden by aligning generator behavior with C++ class metadata. Verification included end-to-end builds (core, imgproc, calib3d, ximgproc, js) with emcmake Ninja and the opencv_js target, confirming correct binding emission and successful JS target generation.
