The quality of the steel surface is a crucial parameter. An improved method based on machine vision for steel surface defects detection is proposed. The experiment is based on 20 images for each of 6 distinct steel defects, a total of 120 defective images achieved from the detection system. 128 different features are extracted from the images and feature(More)
As a visual inspection system can’t meet all the testing demands of various types of piston assembly, a visual inspection reconfigurable model for piston assembly was designed. A five-layer gray box model was established based on analyzing the process of visual inspection, and expressed by extension element; On this basis, a foundation scheme library was(More)
*Corresponding author: Mingxing Lin Email: mxlin@sdu.edu.cn Abstract—Traditional fuzzy clustering algorithm is applicable for noiseless image segmentation. However, it is powerless for the images with noise, special point values and defects. An algorithm which combines spatial fuzzy clustering and level set for indoor scene segmentation is proposed in this(More)
Objective: This research aims to explore the clinical curative effect for the treatment peripheral nerve injury growth factor of Mecobalamin combined with nerve. Methods: 150 cases of patients with peripheral nerve injury treated in the hospital in July were selected from 2011 to 2013. Those patients were randomly divided into three groups according to the(More)
