Application of Phase Congruency n the Image Segmentation of Greige Defects

Yihong Wang


In view of that the texture interferes with image segmentation of the greige defect, a greige defect image segmentation method based on phase consistency is proposed. Firstly, the phase consistency algorithm is analyzed. Secondly, the phase consistency algorithm is improved based on the characteristics of the greige defect image. Then, adaptive double threshold is adopted, and the image segmentation for the contour image extracted by phase consistency based on Otsu algorithm is carried out. Finally, the experimental verification is carried out. The experimental results show the validity of the method.
