Abstract
Manufacturing industries are strongly motivated to use high precision inspection systems with low installation and maintenance cost, as well as the possibilities for reduction in time consumption and effort that they represent. This study improves ceramic tile factories' classification of their products in terms of the size measuring investigation. The objective of this research is to develop an image processing algorithm to measure the length of ceramic tiles. A visual inspection system for ceramic tiles is selected to evaluate the proposed algorithm in a real experimental environment. The result shows that the maximum error in length measurement is less than 2 mm. (C) 2013 The Authors. Published by Elsevier Ltd.
