The mathematical morphology of paper's defect detection method based on multi-scale and multi-structure elements morphology

摘要

Since mathematic morphology of paper's defect detection method based on single-structure element has the shortcoming of obtaining incomplete and discontinued defect information, a new method of mathematical morphology defect detection on paper image using multi-scale and multi-structure elements morphology was proposed. Firstly, on the same scale, the multi-structure elements were adopted in edge detection on paper image, and then the edge image on one scale was gained through synthesizing. Secondly, the edge images on the different scales were weighted summed, binarized and suppressed the noise, and at last, the edge image of paper's defect detection was obtained using multi-scale and multi-structure elements morphology. The results of simulation show that the algorithm in this paper has better anti-interference and positioning accuracy, and the obtained edge is more complete.
