摘要
基于以灰色系统理论为基础的灰色关联度图像边缘检测方法,本文提出了一种基于灰色关联度与经典的Prewitt边缘检测算子相结合的图像边缘检测新方法。该方法把Prewitt算子作参考序列,计算图像各像素点及其八邻域形成的行为序列和参考序列之间的灰色关联度,然后根据灰色关联度来判断检测边缘。实验结果表明,该方法能够较为准确地检测出有用的边缘信息,且具有一定的抗噪声能力,是一种有效的、可行的边缘检测新方法。
Based on the method of image edge detection on gray correlation degree of Gray System Theory,a novel method for imageedge detection is presented based on grey correlation degree and the classical Prewitt edge detection operator. The method is to takethe Prewitt operator as reference sequence,and calculate the grey correlation degree of the image pixels,and between the behavioralsequence and reference sequence in the eight neighborhoods. Then the edge is detected according to the grey correlation degree. Sim-ulations show that this method can detect the useful information of the image edge more accurately and has some anti-noise ability.So this technique is a new effective and feasible method for edge detection.
