| Abstract: | A progressive coding algorithm for three-dimensional (3-D) PointTexture images is proposed in this work. The proposed algorithm represents a PointTexture image hierarchically using an octree.Then, the geometry information is encoded by the predictive partial matching (PPM) method, while the color information is encoded using the discrete cosine transform (DCT). The encoder achieves the progressive transmission of 3-D images by transmitting octree nodes in a top-down manner. We develop a transmission scheme, based on the rate-distortion (R-D) optimization in order to maximize the image quality subject to a given bit budget. Simulation results demonstrate that the proposed algorithm is an efficient method for progressive transmission of 3-D data. | ||
