Chenguangzhi developed two core image preprocessing features for the ECLAIR-Robotics/PCR_Automation repository, focusing on enhancing automated inspection in PCR workflows. Using Python and OpenCV, Chenguangzhi implemented a script that improves image contrast, converts images to grayscale, and detects contours through pixel difference analysis, with configurable contrast and robust boundary handling for diverse image sizes. The work included dynamic, quantile-based contrast adjustment to adapt processing across varying images. Emphasis was placed on code maintainability through refactoring, type safety, and clearer output handling. The engineering demonstrated depth in computer vision and image processing, with reusable, well-structured components and strong input validation.

Nov 1, 20242024-11 PCR_Automation monthly summary: Delivered two primary image preprocessing features to enhance automated inspection reliability in PCR workflows. Key results include (1) Image Contrast Enhancement and Contour Detection Script: OpenCV-based module that enhances image contrast, performs grayscale conversion, and detects outlines via pixel differences. It includes a configurable contrast function and robust output handling; main logic moved under __main__; improved contour boundary handling for diverse image sizes. Commits contributing to this feature include f35c4ea35cc22e0aa36c1f3caca60ed4940b4eeb, 038f2b9621f0bf84867e2c0526dc3e8408884d20, and ef552706d404bf4632f73fa67d41b283eff55165. (2) Image Contrast Adjustment Improvements: enhancements to the contrast workflow with dynamic, quantile-based contrast factors for better adaptability across images; builds on a separate script for applying contrast to images. Commits: e8534a0b64639e3c55c54d03329273951c3ee137 and 98189562260e34f9621d8749a3d02a5ecfbdb9b7. (3) Overall: Refactoring for reusability, type safety, and clearer output handling to improve maintainability and reduce runtime errors.
