Bitplane coding technique for 3-D animated meshes

Abstract

This study presents a novel approach of progressive transmission of 3D animated mesh for different level of details. A typical 3D animation consists of large coherence between frames which can be effectively tapped to achieve compression and by coupling it to the proposed bit plane encoding scheme in the transform domain, efficient generation of progressive 3D animated model can be achieved. Our method is lossless in nature as it does not require addition quantization. In addition, the algorithm can be directly applied on the floating numbers of the mesh. From the experimental result, it can be shown that progressive quality of the animated mesh measured by SNR (dB) can be realized given more bit stream received at the decoder.
