Abstract

In order to improve segmentation of spray painting character in the slab surface, in this paper, we propose to improve the picture quality by image enhancement and filtering, segmenting image from coarse to fine to solve problem in character image segmentation stage step by step. Local dynamic thresholding method is constructed for string localization. Character segmentation algorithm based on morphology, connected component analysis and secondary segmentation to solve the problem of adhesion and fracture present in the images collected in industrial locale environment. Filter with mask used for protecting characters is proposed to solve thin line noise problems. We establish an experimental system to study, results shows that the method has a good effect on adhesion, fracture type and line-interfered image.
