Abstract

Image processing has become a topic of high relevance for automated product inspection in industrial manufacturing. A typical problem is the examination of structured surfaces of textiles to identify or classify defects. Product inspection under real-time conditions requires very powerful image processing systems which motivates the implementation of optical system concepts. In this paper we present a prototype of a coherent-optical processor which is used for the detection of defects in textile web images at video frame rate. After discussing the processor architecture and its underlying filter concept experimental results demonstrate the applicability of the system which is proposed to work as preprocessor in an opto-electronic image processing system.
