Abstract
A scheme for the region of interest (ROI) coding of 3D meshes is proposed for the first time. The ROI is encoded with higher fidelity than the rest region, and the priority of ROI relative to the rest region (background, BG) can be specified by encoder or decoder (user). Wavelet transform is used on 3D mesh and zerotrees are adopted to organize the coefficients. The wavelet coefficients of ROI are scaled up and encoded with a modified set partitioning in hierarchical trees (SPIHT) algorithm. In additional, a fast algorithm is proposed for creating the ROI mask. Once the quality of reconstructed ROI becomes high enough, the transmission can be intermitted and much transmission bandwidth and storage space will be saved consequently.
