During December 2025, Galina Bykova contributed to the opencv/opencv repository by addressing a bug in the polygon approximation algorithm. She improved the accuracy of the approxPolyDP function by refining the distance calculation method, ensuring it measured the distance from a point to a segment rather than to a line. This adjustment enhanced the reliability of contour-based representations in computer vision pipelines. Galina implemented the fix using C++ and reinforced its correctness with a dedicated regression test, demonstrating her skills in algorithm development and unit testing. Her focused work provided a deeper, more robust solution for downstream applications relying on OpenCV.
