Abstract:In this dissertation, we study issues related to free-view 3D-video, and in particular issues of 3D scene reconstruction, compression, and rendering. We present four main contributions. First, we present a novel algorithm which performs surface reconstruction from planar arrays of cameras and generates dense depth maps with multiple values per pixel. Second, we introduce a novel codec for the static depth-image-based representation, which jointly estimates and encodes the unknown depth map from multiple views using a novel rate-distortion optimization scheme. Third, we propose a second novel codec for the static depth-image-based representation, which relies on a shape-adaptive wavelet transform and an explicit representation of the locations of major depth edges to achieve major rate-distortion gains. Finally, we propose a novel algorithm to extract the side information in the context of distributed video coding of 3D scenes.
