Nathanchase22
Nathan Chen developed and maintained the ECLAIR-Robotics/PCR_Automation repository over seven months, focusing on computer vision pipelines for automated number detection and robotic control. He engineered robust image preprocessing and cropping workflows using Python, C, and OpenCV, integrating C-accelerated modules for performance and cross-platform compatibility. His work included modular refactoring, multithreaded image processing, and OCR tuning with Tesseract, resulting in improved accuracy and reliability. Nathan also implemented Dockerized development environments, automated environment setup with Makefiles and conda, and a JSON-based TCP/ROS bridge for remote robotic arm control, demonstrating depth in backend development, build automation, and system integration.

Dec 1, 2024December 2024 monthly delivery focused on robustness, performance, and end-to-end testability of the PCR_Automation workflow. Implemented a C-accelerated, skew-aware image preprocessing and cropping pipeline with refined masking and contour-based bounding boxes, boosting number-detection accuracy and processing speed. Also delivered camera-feed integration into the detection module, simplified image input handling (read_img accepts image objects), and enhanced testing tooling for flexible single or multi-test execution, while removing unused camera/test code to reduce maintenance overhead.
