| Abstract |
The image processing described in this paper is used for visual quality control in ceramic tile
production. The tiles surface quality is described by the surface defects. The described image
processing is based on the discrete wavelet transform method. The diagnostic algorithm is described.
It is based on comparing of the wavelet coefficients of the original image without surface defects and
the real images of ceramic tiles. The method is verified by using the artificial defects on the image and
sensitivity testing on failure contrast and size is done. The algorithm is evaluated experimentaly using
the real tile images. The analysis of the detection capabilities and sensitivity expressed in nondetected
failures and false proclaimed defect is done also. Optimal connection between the segment size and
DSL for each type of surface failure could be used to make efficient system for quality control and
failure classification in automated production process. |
