The typical kind of perturbations expected are waves, steps, and bumps, and automatic classification into the classes is desired. Various possible methods of analysis were pro- posed and studied in some detail, including projection onto suitable basis functions, wavelets, and radial basis functions. Other methods were studied in less detail, but with the aim of giving a digital signature of defects that could be used to classify them. date: 2012 citation: Allwright, D.J. and Chen, Yujia and Gower, Artur and Lam, Kei Fong and Chakhchoukh, Amine and Cowley, Stephen and Alistair, Forbes and Guterman, Alexander and Hammerton, Paul and Jia, Dewei and Klimek, Aleksander and McCarthy, Michael and Rockstroh, Parousia and Ziolo, Piotr (2012) Efficient description of shape perturbations.
