Abstract

In this paper, we propose a modified 3-D SPIHT algorithm with 3-D resizing, which is especially targeted for low bit rate compression. In the proposed algorithm, we first reduce 3-D images using a 3-D interpolation algorithm and encode the reduced 3-D images using a 3-D SPIHT algorithm. At the decoder, the encoded bit stream is first decoded and the reconstructed 3-D images are enlarged to the original image size. Experimental results show that the proposed algorithm outperforms the conventional 3-D SPIHT algorithm at low bit rates.
