摘要
本文提出了一种基于多重分形分析的边缘检测算法。该算法通过定义在图像灰度级上的测度,计算图像中每一个象素点的奇异性和它的多重分形谱,然后根据多重分形谱,提取图像的边缘信息。经试验表明,该算法具有良好的边缘检测效果,并能突出主要的图像边缘细节信息。
A multifractal analysis approach to the problem of image edge detection is proposed. Based on the measure of image grayscale, singularity of each pixel in the image and its multifractal spectrum are calculated, accordingly, the edge information of image is given. Experiment result demonstrates that this approach is effective for edge detection, giving the eminent and detailed edge information of the image.
