基于联系度态势的图像边缘检测算法

Algorithms of image edge detection based on degree connection situation

为了使提取的目标边缘精确、连续、清晰以及具有抗噪声干扰能力,这里给出了一种新的基于联系度态势的边缘检测算法。该算法是以Sobel算子为基础,先对图像进行灰度变换,然后运用联系度态势中的同一度和对立度之间的趋势关系,对图像目标实现边缘检测。实验结果表明,该算法不仅计算速度快,而且检测的目标边缘准确、清晰,且对噪声的抑制能力强。

In order to make the object brim pick-up accurate, continuous, legible and have the capability of suppressing the noise, a new algorithm of image edge detection that based on degree connection situation is presented. The algorithm is based on Sobel operator. Firstly, it processed the image to gray-scale transformation. Secondly, it used the trend relationship between the degree of identity and opposition in a degree connection situation to accomplish detecting image edge detection. The result of simulation indicates that this method is not only fast in rtmtime but also accurate and legible in object brim pick-up; furthermore, the noise is greatly suppressed by using it.
