Worked on the PaddleOCR repository, focusing on targeted improvements to both code and documentation over a two-month period. Delivered an OCR preprocessing enhancement by changing the border padding color from black to gray, which improved OCR accuracy and required updates to C++ image processing logic and CMake configuration for better cross-platform compatibility. Addressed a Windows YAML-CPP static linking issue, ensuring smoother builds. In a subsequent cycle, concentrated on documentation quality by correcting a parameter typo and clarifying usage instructions, reducing user misconfigurations. Maintained a disciplined approach to code quality, documentation standards, and stability, leveraging C++, CMake, and image processing expertise.
