Colour Texture Analysis - Defect Detection on Tile SurfacesThis project aims to develop a system which is capable of detecting colour and/or texture defects on ceramic tile surfaces. The ceramic tiles manufacturing process has now been completely automated with the exception of the stages of production concerned with visual inspection. Post-production inspection has been dealt with in recent years, but in-production processes have not. These are still performed manually in order to reject those products found with defects and pattern faults. This European funded project is concerned with the problem of automatic inspection of ceramic tiles using computer vision at various stages during production. By tracing the defective tiles, the project intends to determine the cause of the defect generation, and hence take steps to control and recalibrate the production processes. Amongst the types of defects we aim to look for are colour shade tonality across textured tiles as well as surface defects such as densely printed textures or geometric textural defects. The project is funded by EC project G1RD-CT-2002-00783 MONOTONE (Automatic Quality Control for Industrial Printing).  Staff and Students
