MediaPipe GUI is a Python desktop application that wraps multiple MediaPipe vision pipelines into a single interactive interface, letting users run tools like Hands, Pose, Face Mesh, Face Detection, Object Detection, and Gesture Recognition on either a live camera feed or prerecorded video. The project provides real-time annotated preview, structured JSON results, logging, and performance metrics such as FPS and frame latency, while also supporting exports like saved frames, results JSON, and recorded annotated video. Its plugin-based architecture makes it easy to extend with new pipelines, so it works well as a reusable computer vision front end for experimenting with perception models, debugging outputs, and building future AI-powered analysis features.
