摘要
随着三维网格在数字游戏、影视动画、虚拟现实等领域的广泛应用,针对三维网格的处理方法也越来越多,包括压缩、简化、嵌入水印和去噪等,这些处理技术均不可避免地导致三维网格的失真。如何更好地评估三维网格的视觉质量成为目前亟需解决的问题。回顾了近20年来发展起来的三维网格的客观质量评价方法。介绍了这一领域常用评价方法的技术指标以及常用的数据库;对现有的典型三维网格的质量评价方法进行了分类并介绍了其各自的特点;在常用的数据库上对所介绍的典型算法进行性能测试和比较;对三维网格客观质量评价方法进行了总结与展望。
Abstract
With the wide applications of three-dimensional (3D) meshes in digital entertainment, television animation, virtual reality, and other fields, there are more and more processing techniques for 3D meshes, including compression, simplification, watermarking, and denoising. These processing techniques will inevitably lead to various distortions in 3D meshes. Therefore, how to preferably evaluate the visual quality of 3D meshes becomes an urgent problem to be solved at present. This paper reviews the objective quality assessment methods for 3D meshes developed during the past 20 years. First, some technical indexes for 3D mesh quality assessment and several public databases are introduced. Second, the quality assessment methods for existing typical three-dimensional meshes are classified, and their respective characteristics are introduced. Then, the typical algorithms introduced in the commonly used databases are tested and compared. Finally, the objective quality assessment methods of 3D meshes are summarized and prospected.
