| 摘 要： | 医学图像边缘检测在医学图像处理中起着非常重要的作用,基于克隆技术提出一种医学图像边缘克隆算法,首先分析克隆技术并进行数学建模,在此基础上,分析医学图像边缘克隆原理,提出激活因子猜想,通过激活因子,构造出权重因子函数。然后,利用复制理论,得到克隆函数。结合人类视觉特性,给出边缘克隆的阀值选取方法。最后给出仿真结果,并与Canny算子检测的边缘进行比较,证明算法具有更好的边缘识别性能。

| Abstract: | Edge detection of medical image is important in medical image processing. We suggested an algorithm of medical image edge clone based on clone technique. First of all, we analyzed the principal of clone technique and built mathematical model of clone technique, then we analyzed principal of edge clone, supposed activation gene and constructed weight gene function. We obtained clone function by using duplicating theory. With human visual properties, method of threshold choice in edge clone was suggested. As a result, simulation experiments compare with the result of edge detection of Canny Operator, and demonstrate better edge recognition capability of the algorithm. |
