Systems concept for visual texture change detection strategy

Abstract

The goals of this paper is to develop effective algorithms to achieve acceptable performance in what we call Visually Detectable Defects (V.D.D); and also to define from systems concepts a test strategy. The main problem in V.D.D. has been finally identified as that of the detection and labelling of subtle changes in the texture of an image. In consequence, none of the standard procedures for texture discrimination gave good results, so that increasing the complexity of the process was decided upon, to provide a new decision level.
