Human101 is a framework for quickly reconstructing human figures from a single view. It can train a 3D Gaussian model within 100 seconds and render images at a resolution of 1024 and above 60FPS without pre-saving the Gaussian properties of each frame. The Human101 pipeline is as follows: first, extract 2D human pose from the single-view video. Then, use the pose to drive a 3D simulator to generate corresponding 3D skeletal animation. Finally, construct a time-varying 3D Gaussian model based on the animation for real-time rendering.
