摘要： 细分小波近年来发展迅速，在计算机图形显示、渐进网格传输和网格多分辨率编辑等领域获得了广泛的应用。Bertram提出的Loop细分小波是基于提升格式的双正交细分小波的典型范例，它所针对的对象均为网格的内部顶点。目前尚未发现相关文献提及细分小波对于边界的处理。该文在Loop细分小波算法的基础上，给出了一种Loop细分小波边界处理的方法，经验证效果令人满意。

Abstract: Subdivision wavelets have been developed very fast in recent years. They are widely used in computer graphics, progressive transmission and multiresolution editing etc. Based on the lifting scheme, Bertram has introduced a bi-orthogonal wavelet construction for the Loop subdivision. The vertexes involved in the Bertram’s method are all inner ones in the subdivision surface. The paper presents a method to deal with the boundary of the mesh with subdivision wavelets. Tests show the feasibility of the approach.
