A shape from texture method based on local scales extraction: precision and results
Justin Plantier, Sylvie Lelandais, Laurent Boutté · 2002
We propose a "shape from texture" method computed on two steps. First a new local scales extraction technique is proposed. The local scale of each point of the picture is computed from an interpolation of wavelet values. Then an interpolation of the local scale map is developed. The method used is an improvement on the one introduced by Lu et al., (1996). It consists of making a local scales interpolation of a textured slope plane's picture, to recover its orientation under the perspective projection model. The aim of this paper is also to present the precision that we have to expect from these methods. We study the influence of the different parameters to the results. To end we compare our results with Lu's one on about a hundred textured plane pictures. These results confirm the precision study.
