- W2377094648 abstract "A non-progressive triangle mesh compression method based on wavelet transform is proposed in this paper. It uses remeshing to remove most of the connectivity information, then uses wavelet transform to compress the geometry information by taking advantage of its strong decorrelation power. After remeshing and wavelet transform, all wavelet coefficients are scanned in a determined way to form a sequence, then quantized and arithmetic encoded. For the adaptive semi-regular sampling pattern obtained by remeshing, in order for the decoder to know at which vertex each wavelet coefficient locates, an adaptive subdivision information coding algorithm is also designed. Experimental results show that the proposed method has achieved better rate-distortion performance than the well-known Edgebreaker method, and the compression ratio is about 200:1 for complex meshes acquired by 3D scanner under 10 bits quantization, which is more than 2 times of that of Edgebreaker method." @default.
