| 中文摘要: |
| 通过对褶皱纸病的分析研究,提出一种基于改进Hough变换的检测方法。利用边缘检测对纸病信息进行去噪和简单提取,采取Hough变换的方法将纸张从图像灰度空间转换到参数空间,从变换后的参数空间中提取纸病图像中的褶皱特征并进行识别。实验结果表明,此方法识别率高、计算速度快、检测效果好。 |
| Abstract: |
| A new method based on improved Hough transform is proposed for detecting paper defects such as fold, crease. The method of edge detection can eliminate noise and extract the information of paper, the paper image is transformed from grey space to parameter space from which the characteristics of fold in the paper image are extracted and identified. The experimental results demonstrate that this method has high recognition rate and fast calculation. |
