| Abstract:The complicated paper surface defects such as wrinkle and crease with linear features which have close slope or intercept cannot be distinguished effectively by traditional Hough transform. Based on existing algorithm, the Hough space is transformed into two-dimensional image, and then the paper defects features are extracted, through which the wrinkle and crease surface defects can be detected more accurately. Finally, the experiment proves that the improved algorithm has higher detection precision and shorter time consumption compared with Hough transform. |
