摘要
在机器视觉领域中,图像边缘检测是一项重要技术,可以为后期的图像处理进行必要的前期准备,而准确的评判出所处理图像的边缘检测效果更是一项关键技术。本文在基于Canny的边缘检测三准则的基础上,提出了新的三准则。通过理论分析,为新三准则赋予了三个数值定量的基础评判指标,即边缘检测图像重构相似度SSIM指标、边缘可靠性BIdx指标以及边缘连续性CIdx指标,然后将三个基础评判指标进行融合,得到图像边缘检测客观评价指标EIdx。最后通过实验数据表明,该方法对图像边缘检测效果评判所具有的精确性明显优于主观评价体系所具有的不确定性。
In the field of machine vision, image edge detection is an important technology.It can prepare necessity for the image processing,however,edge detection and accurate evaluation of the effect of image processing is a key technology. This article is based on Canny edge detection three criterion and proposed three new criterion.Through theoretical analysis, the basic evaluation index gives three numerical quantitative for the new three criteria, edge reconstruction similarity index SSIM,edge reliability index BIdx and edge continuity index CIdx,then the three basic evaluation indexes are obtained fusion, and achieve image edge detection and objective evaluation index EIdx. Finally, through the experimental data show that, this method with the accuracy is obviously better than the subjective evaluation system.
