In this paper, we explore the use of over-complete spherical wavelets in shape analysis of closed 2D surfaces. Previous work has demonstrated, theoretically and practically, the advantages of overcomplete over bi-orthogonal spherical wavelets. Here we present a detailed formulation of over-complete wavelets, as well as shape analysis experiments of cortical folding development using them. Our experiments verify in a quantitative fashion existing qualitative theories of neuroanatomical development. Furthermore, the experiments reveal novel insights into neuro-anatomical development not previously documented.
在本文中,我们探讨了过完备球面小波在封闭二维曲面形状分析中的应用。先前的工作已在理论和实践上证明了过完备小波相对于双正交球面小波的优势。在此,我们给出了过完备小波的详细公式,以及使用它们进行皮质折叠发育形状分析的实验。我们的实验以定量方式验证了现有的神经解剖发育定性理论。此外,这些实验还揭示了此前未记录的关于神经解剖发育的新见解。
