Application Of Mathematical Morphology In Fabric Defects

In fabric industry, the quality of control and detection is very important. Detection of defects is the most important part. Even to nowadays, in most fabric factories, operators beside the product line watch the running fabric and decide whether defects occur or not. This artificial method has much shortcoming, such as omitting defects, confusing defects, and the worst is bad efficiency. So in order to realize automation of defecting, recent years many experts focus on this research topic. The total number of fabric defects is large and it is nearly impossible to find a common pattern reorganization algorithm. In all the defects, the numbers of hole, warp-lacking and weft-lacking are the largest.The use of Morphological Operations in the detections of fabric defects is mostly discussed in this paper. The author designs a system by MATLAB to emphatically detect the defects of hole, warp-lacking and weft-lacking. The reliability of Morphological Operations is tested based on experiments. After using the traditional method of Morphological Operations, the author uses morphological opening again in order to remove noise and stand out the defects.In Chapter 1, first, introduce the statement of fabric defects detecting and achievement foreign and home experts have acquired in this field.In Chapter 2, introduce some mathematical tools and image processing...
