Computer-aided visual inspection

The quality control in industrial processes and production lines is increasingly rigorous due to governmental issues and the competition among other industries. These make new studies in this field even more important, especially on defects analysis and visual inspection. Among the methods of inspections commonly used the highlighted ones include the direct inspection that is performed without the aid of optical devices, and the remote inspection that makes use of optical instruments, both having an inspector responsible for a subjective evaluation. Such methods are usually the first used in quality control of products. In this paper we propose a remote and automatic computational image analysis to verify the presence of defects in products in a production line.
