Texture analysis on slightly curved surfaces

: Nickolay, B.; Wieland, T.

Abstract
Quality examination of material surfaces is increasingly made with the use of methods of digital image evaluation. However, these are based on a plane surface reproduced in central perspective on a CCD quantitative study of the suitability of methods of 2D texture analysis for inspecting slightly curved surfaces. Furthermore, an approach is presented for a method of analyzing such three-dimensionally configurated textures.
