| 摘 要： | 阈值法是图像分割中的重要方法,并在图像处理中得到了广泛的应用。针对电子扫描显微镜(SEM)摄取的纤维材料图像的自身特性,在预处理的基础上,提出了一种基于二维灰度直方图的人工鱼群图像分割方法。二维直方图的阈值的选取,是一个求全局最优的优化问题,本文将人工鱼群的算法应用于图像分割中,利用人工鱼群算法寻求二维熵的最优值,在实验中,人工鱼群算法收敛速度快,结果稳定,取得了理想的效果。

| Abstract: | Thresholding is an important method of image segmentation and is extensively used in image processing for many applications.The fibrous material image captured from scanning electronic microscopy(SEM)shows the porosity surface structure characters of the material.To some extent,quantity analysis of material image is necessary for material study.In the paper,a method of image segmentation by artificial fish swarm algorithm based on two-dimensional gray histogram is presented after pretreatment.According to t... |
