Abstract :
Three-dimensional (3-D) mesh sequences using the principal component analysis technique are encoded. First, rate and distortion models for principal components are developed and then a rate-distortion optimised quantisation scheme is proposed. Simulation results show that the proposed algorithm provides a much higher coding gain than conventional coders.
