最后，通过把球面参数化算法和自适应采样算法扩展到平面，我们提出一种基于传统图像压缩技术的几何信号压缩算法。
At last, by generalizing our spherical parameterization algorithm and adaptive sampling scheme to the planar case, we can adopt image compression algorithms to compress geometric signals.
将亏格为零的三维模型进行球面参数化的方法大致可以分成3类：(1)基于累进网格的方法(2)球面松弛的方法(3)保角参数化方法。
These methods can be divided into three: (1) method based on progressive mesh (2) method based on sphere relaxation (3) conformal method. The three methods have their own advantages and shortcomings.
