Abstract
In this paper, a simple yet highly effective video compression technique is presented. The zerotree method by Said, which is an improved version of Shapiro's original one, is applied and expanded to three-dimension to encode image sequences. A three-dimensional subband transformation on the image sequences is first performed, and the transformed information is then encoded using the zerotree coding scheme. The algorithm achieves results comparable to MPEG-2, without the complexity of motion compensation. The reconstructed image sequences have no blocking effects at very low rates, and the transmission is progressive.
