Abstract:
We present an image-based technique for relighting dynamic human performances under spatially varying illumination. Our system generates a time-multiplexed LED basis and a geometric model recovered from high-speed structured light patterns. The geometric model is used to scale the intensity of each pixel differently according to its 3D position within the spatially varying illumination volume. This yields a first-order approximation of the correct appearance under the spatially varying illumination. A global illumination process removes indirect illumination from the original lighting basis and simulates spatially varying indirect illumination. We demonstrate this technique for a human performance under several spatially varying lighting environments.
