基于Prewitt算子和邓氏关联度的图像边缘检测算法

Algorithm of image edge detection based on Prewitt operator and Deng interrelatedness

边缘是图像最重要的特征之一,其检测的好坏对图像的识别和分割的效果有直接的影响,本文探讨了传统的Prewitt算子和灰色关联度在边缘检测中的应用情况,提出并实现了一种将Prewitt算子和邓氏关联度相结合的边缘检测方法。实验表明,该方法提取的边缘较完整、连续性好、非边缘点少,为图像边缘检测探索了一种新的途径和方法。

Edges is the most important feature of the image. The quality of image edge has a di- rect impact on the results of image recognition and segmentation. The application of traditional Pre- witt operator and gray relational grade in edge detection was discussed, and a method of image edge detection combining Prewitt operator with Deng interrelatedness was proposed and implemented this paper. The experiment proves that edge extracted tion and consecutiveness and fewer non - edge points. by the combining method show more comple- This paper explore a new method for image edge detection.
