Analyses show that Block Adaptive Quantization(BAQ)still is the best choice while Block Adaptive Vector Quantization(BAVQ)performs best when compression ratio becomes high and Restricted Polar Quantization(RPQ)does between the above two.
仿真结果表明三种算法各有其适用范围,块自适应量化(BAQ)仍是压缩比不高时的首选,块自适应矢量量化(BAVQ)在压缩比高时性能较好,而约束式极坐标量化(RPQ)的复杂度和性能均介于二者之间。
The survey of developments,applications and research prospects of piece-linear mesh editing approaches is presented in this paper in algorithms sense,and recent appearing intrinsic approach,as-rigid-as-possible interpolating,optimizing coordinate algorithm and differential mesh editing are investigated with details.
