Worked on enhancing the reliability and maintainability of face landmark overlay rendering in the google-ai-edge/mediapipe-samples repository. Focused on improving the OverlayView component by addressing scaling and centering issues, and introduced helper utilities to streamline the drawing of landmarks and connectors. Utilized Kotlin and applied expertise in Android development, computer vision, and graphics rendering to ensure overlays behaved robustly, especially when no face landmarks were detected, thereby reducing UI glitches. Fixed a translation-related bug in the overlay, resulting in clearer and more stable demo behavior. The work emphasized maintainable code and a smoother user experience for sample applications.
