Full-Body Animation From Expression Input With Real-Time Motion Analysis

The patent replaces the mechanical green screen capture system with a computational image processing system. Instead of using physical dot suits and multiple cameras to capture motion data, the system uses algorithms to automatically detect and track facial landmarks, body pose, and motion from ordinary video recordings. This substitution eliminates the need for specialized studios and post-production processing, enabling real-time animation generation from standard video inputs.

The patent makes the animation system universal by enabling it to work with ordinary video recording devices instead of requiring specialized green screen studios and multiple cameras. The same system can process various input types including facial expressions, body pose, and full-body motion from standard webcams, smartphones, or video recordings, eliminating the need for complex specialized equipment while maintaining animation quality.

The patent performs preliminary action by automatically detecting and extracting motion data from video frames in real-time during the recording process itself, rather than requiring post-production processing. The system continuously tracks facial landmarks, body pose, and motion vectors as the video is being recorded, preparing the animation data on-the-fly without requiring subsequent manual processing steps.

The patent segments the complex animation processing into distinct modular components: facial landmark detection, body pose estimation, motion vector calculation, and animation synthesis. Each module processes specific aspects of the input independently, allowing for optimized computational resource allocation. This segmentation enables real-time processing by breaking down the computationally intensive task into smaller, more manageable operations that can be executed efficiently.
