| 摘 要： | 针对Roberts算子容易漏检及对噪声较敏感的问题,提出一种改进的基于灰色关联分析方法的边缘检测算法GRA-Roberts.通过改进Roberts算子提高其检测精度和抗噪性能,结合灰色关联分析方法,将改进后的Roberts算子作为参考序列,通过计算灰色关联度来检测图像边缘.实验结果表明,GRA-Roberts算法能有效克服Roberts算子算法易漏检和对噪声敏感的问题,且比其他灰色关联结合算法具有更好的检测效果.

| Abstract: | Aiming at the problems of Roberts operator being easy to miss detection pixels and sensitive to noise, an improved edge detection algorithm GRA-Roberts is proposed. By improving the Roberts operator, the precision and the anti-noise performance is enhanced. Combined with the grey relational analysis, referring to the improved Roberts operator, the image edge is detected based on the grey relational grade. The experiment results show that GRA-Roberts can not only get over the above drawbacks of the Roberts operator algorithm effectively, but also get better detection effects compared to other related grey relational algorithms. |
