Abstract :
In this paper we propose a 3D image compression method which is volume rendering oriented and uses wavelet transforms. Using a separable wavelet transform, the dataset is decomposed into subbands with different importance to the rendering process. According to this difference, an efficient classified quantization and a bit allocation strategy are designed, and a zero-tree structure is used to represent zero coefficients
