A Fast Defect Detection Algorithm for Glass Tube Based on ROI Reduction

In this paper, we present an algorithm for defect detection in glass products that allows us to minimize the processing time. The main idea is based on the reduction of the size of the image area to investigate by using the features of glass images. Results on a set of test images show that the proposed solution does not compromise the quality of the detection and allows to achieve an improvement of a factor of 7x compared to the existing solution under particular conditions, with the same accuracy in defect detection
