边缘是图像最基本的特征,是图像分割的第一步。经典的边缘检测方法如:Roberts,Sobel,Prewitt,Kirsch,Laplace等方法,基本都是对原始图像中象素的小邻域构造边缘检测算子,进行一阶微分或二阶微分运算,求得梯度最大值或二阶导数的过零点,最后选取适当的阀值提取边界。由于这些算法涉及梯度的运算,因此均存在对噪声敏感、计算量大等缺点。在实践中,发现SUSAN算法只基于对周边象素的灰度比较,完全不涉及梯度的运算,因此其抗噪声能力很强,运算量也比较小。并将SUSAN算法用于多类图像的边缘检测中,实验证明该算法非常适合含噪图像的边缘检测。 2 SUSAN边缘检测简介

多目标优化算法
说明: 工程实际中的许多优化问题是多目标的优化设计问题。通常情况下多个目标是处于冲突状态的,不存在一个最优设计使所有的目标同时达到最优,一个目标性能的改善,往往以其它一个或多个目标性能的降低为代价。无论采用自适应遗传算法还是其它在标准遗传算法基础上经过改进的遗传算法,如果采用加权组合法等将多目标转化为单目标的处理方法,就无法充分发挥遗传算法的优势。如果把遗传 算法与适用于多目标处理的几此协方法相结合,就能完全发挥遗传算法在多目标优化设计中的作用。(Many optimization problems in engineering practice are multi-objective optimization design problems. Generally, multiple goals are in conflict. There is no one optimal design to achieve all goals simultaneously. The improvement of one goal's performance is often at the expense of the performance of one or more other goals. Whether adaptive genetic algorithm or other improved genetic algorithm based on standard genetic algorithm is adopted, if weighted combination method is adopted to transform multi-objective into single-objective processing method, the advantages of genetic algorithm cannot be fully utilized. If the genetic algorithm is combined with several cooperative methods suitable for multi-objective processing, the role of genetic algorithm in multi-objective optimal design can be fully exerted.)
