摘要:
边缘是指与周围灰度变化极大的像素点的集合,是图像最重要的特征之一。边缘检测的实质是采用某种算法来提取出图像中对象与背景之间的交界线。 文中利用三种二进小波滤波器,分别进行模极大值法的边缘检测处理,并比较得到的边缘信息。 二进小波变换平移不变性的优点保证了图像变换后像素的位置不发生偏移。 因此二进小波变换可以完整地保留图像的信息,从而能够描述图像的局部特异性。将此实验结果与 Canny 算子的边缘检测结果进行比较,二进小波模极大值法的边缘检测效果更好,在图像处理的精度方面取得了较好的处理效果。
Abstract:
Edge refers to the collection of pixels with great changes in the surrounding gray scale,which is one of the most important features of an image. The essence of the edge detection is to use some algorithm to extract the image boundary between the object and the background. In this paper,three kinds of dyadic wavelet filters are used to detect the edges of the modulus maxima method respectively, and the edge information is compared. The advantages of translation invariance of dyadic wavelet transform ensure that the position of pixels will not be offset after image transformation,so dyadic wavelet transform can intact image information, which can describe the image of local specificity. Comparing the experimental results with the edge detection results of Canny operator,the edge detection effect of dyadic wavelet modulus maxima method is better. The processing effect is better in the aspect of image processing accuracy.
