Abstract:

IBR is a new scheme which can represent scenes, and it offers a quick way to model and render a realistic 3D scene. But the data produced by this method is huge. In this paper, we give a scheme to compress the image array. Our scheme first selects the image array we need urgently, and then applies a l   ifting-based 3D wavelet transform on the selected image array, and finally quantizes different bands with different precisions and entropy codes for each band. The experiments show that this scheme can achieve very good results.

Key words: （IBR, 3D wavelet transform, lifting scheme, EZW）
