dc.description.abstractThis paper deals with the presentation of an algorithm for acquisition and processing of images, in order to obtain information of topologic aspects in a 3D surface, starting from 2D images, by means of the analysis of the shine of the risings of the surface, when this is illuminated by light sources in oblique direction. In the surface, some areas of shine appear corresponding to the areas of the rising surfaces with slopes in front of the illumination source, and shade areas corresponding to the sinking of the surfaces. When obtaining several images of the same area, by illuminating the opposite sides and by realizing operations with them, it is obtained information on the geometry and situation of the relief elements, like elevations and depths of the surface. On this basis a novel algorithm has been developed for the detection of the situations and characteristics of the threads in structures of plane textures, in the process of detection of textile shortcomings.eng
