 Abstract: This paper presents an online system which is capable of reconstructing and rendering dynamic objects in real scenes. We reconstruct visual hulls of the objects by using a shape-from-silhouette approach. During rendering, a novel blending scheme is employed to compose multiple background images. Visibility artifacts on the dynamic object are removed by using opaque projective texture mapping. We also propose a dynamic texture packing technique to improve rendering performance by exploiting region-of-interest information. Our system takes multiple live or pre-recorded video streams as input. It produces realistic real-time rendering results of dynamic objects in their surrounding natural environment in which the user can freely navigate.
