AbstractThis paper studies the rendering and post-processing of a dynamic image-based representation called the simplified dynamic light fields (SDLF) (or plenoptic videos) with depth information. The user viewpoints are limited to a camera line to simplify the capturing and compression processes. By associating each image pixel with its depth value, methods for improving the rendering quality and detecting occlusions are proposed. Due to the limited sampling at depth discontinuities, adaptive lowpass filtering is applied to the detected occluded regions near object boundaries in order to suppress the aliasing artifacts. Rendering results using computer-generated images show that considerable improvement in rendering quality even for dynamic scenes with large depth variations.
