A real-time sausage appearance defect inspection system is presented in this paper. The general hardware and software structure is presented and a model method for sausage defect detection is proposed. This inspection system gives consistent and repeatable satisfactory results under real industrial conditions with sufficient speed.
Discrete Tchebichef moments have been used in some recent image processing applications due to their advantage of preserving the analytical properties. However, the computation of Tchebichef moments is time-consuming. This paper presents a fast Tchebichef transform algorithm for binary images represented by Image Block Representation (IBR). The new algorithm calculates Tchebichef moments of an image...
Based on the different brightness feature of the glue-line and gluing surface, we propose a new method to analyze the glue-line with the help of layered algorithm. The method is suit for different type of gear-box, and the impact of gear-box location inaccuracy is relatively small. The experiment shows that the method is feasible and the quality of glue-line can be accurately inspected.
