This strategy is similar to that employed in our MediaPipe Face Mesh solution, which uses a face detector together with a face landmark model. A hand landmark model that operates on the cropped image region defined by the palm detector and returns high-fidelity 3D hand keypoints.

MediaPipe Hands utilizes an ML pipeline consisting of multiple models working together: A palm detection model that operates on the full image and returns an oriented hand bounding box. Tracked 3D hand landmarks are represented by dots in different shades, with the brighter ones denoting landmarks closer to the camera. We hope that providing this hand perception functionality to the wider research and development community will result in an emergence of creative use cases, stimulating new applications and new research avenues.įig 1. Whereas current state-of-the-art approaches rely primarily on powerful desktop environments for inference, our method achieves real-time performance on a mobile phone, and even scales to multiple hands. It employs machine learning (ML) to infer 21 3D landmarks of a hand from just a single frame. MediaPipe Hands is a high-fidelity hand and finger tracking solution. finger/palm occlusions and hand shakes) and lack high contrast patterns. While coming naturally to people, robust real-time hand perception is a decidedly challenging computer vision task, as hands often occlude themselves or each other (e.g. For example, it can form the basis for sign language understanding and hand gesture control, and can also enable the overlay of digital content and information on top of the physical world in augmented reality. The ability to perceive the shape and motion of hands can be a vital component in improving the user experience across a variety of technological domains and platforms.
