A Unity demo demonstrating hand isolation and display from the raw video passthrough. Push and pull floating blocks with your real hands (tinted to a flesh tone of course).
Ideally suited as a base for further experiments.
Code in non-optimized, and the recursive flood-fill segmentation technique has proven to be too slow for use in a shippable application. Ideally, camera data would be projected from the camera’s position directly onto the hand meshes inside of the vertex shader (netting you segmentation and stereo-correct reprojection in one, cheap operation).
