Title: Automatic Inspection of Defects in Plain and Texture Surfaces
Source: Proceedings of the 2001 IEEE International Conference on Intelligent Engineering Systems (INES 2001) / Patkai, Bela ; Rudas, Imre J. (ed). - Tampere : Institute of Production Engineering, Tampere University of Technology , 2001. 221-227.
Meeting: IEEE International Conference on Intelligent Engineering Systems
Location and date: Helsinki, Finska, 16, -18.09.2001
Keywords: inspection ; defects ; image processing ; tiles ; discrete transform ; wavelet
The image processing used for visual inspection and quality control in a serial production is described in this paper. We used the discrete wavelet transform - DWT in our failure detection algorithm. To achieve robustness as well as good sensitivity of the algorithm, we divide the images into segments. The difference of the wavelet coefficients maxima for the given segment for images of the tile with and without defects was used for defect detection. The analysis of detection capabilities is done for different segment sizes, different detection sensitivity levels - DSL and for two orthogonal wavelets.
