A novel edge feature description method for blur detection in manufacturing processes

A novel inspection sensor by using an edge feature description (efd) algorithm based on a support vector machine (svm) is proposed for industrial inspection of images. this method detects and adaptively segments blurred images by using the proposed algorithm,which uses efd to effectively classify blurred samples and improve the conventional methods of inspecting blurred objects; the algorithm selects and optimally tunes suitable features. the proposed sensor applies a suitable feature-extraction strategy on the basis of the sensing results. experimental results demonstrate that the proposed method outperforms the existing methods. © 2016 tsun-kuo lin.
