Multiscale Analysis, Wavelets and Texture Quality
- Fleeces made from artificial fabric are the basic material for many products, ranging from carpets to napkins. Itturns out that their quality is determined by the distribution of the fibres, which can be measured eithter by the optical transmission properties or by the thickness of the material. In both cases one obtains a 2-dimensional signal and one would like to have an objective quality criterion, based on a suitable analysis of these data, which, moreover, can be automated.; In this paper we propose a solution to this problem, based on multiresolution techniques, which have been developed in image analysis through the last few years. Moreover, we use these techniques to investigate fractal properties of the textures.
