<title>Low-delay embedded 3D wavelet color video coding with SPIHT</title>

Abstract

In this paper, a modification of the 3D SPIHT, which is the 3D extension to image sequence of 2D SPIHT still image coding, is presented in order to allow more flexibility in choosing the number of frames to be processed at one time by introducing unbalanced tree structure. Simulation shows that 3D SPIHT with reduced coding latency still achieves coding result comparable to MPEG-2, and exhibits more uniform PSNR fluctuations. In additional extension to color video coding is accomplished without explicit rate-allocation, and can be used to any color-plane representation.
