论文引入了snake和livewire两种十分流行的医学图像交互分割方法，详细推导snake的能量方程，实现了最小化能量方程的有限差分和greedy两种算法，并利用邻近图像的相似性，将其成功应用于图像序列的分割； livewire是一种象素级的轮廓搜索算法，它在方向图中找到开始点和目标点之间的最小代价路径。
In the case of the maximal observed area model , the complexity of the problem was studied first , and come to the conclusion that this solve problem of this model is a np problem . so , genetic algorithm ( ga ) and greedy algorithm is applied to solve this problem
对空间覆盖率优先问题,分别应用遗传算法及贪婪算法对其实现了近似求解,并通过对这两种不同求解算法的特点及复杂性进行分析,明确了这两种算法的适用条件;随机实验也进一步说明了两种算法的优缺点所在。
To deal with the question that how we can guarantee the dna sequences which are stored in the personal dna database are anonymous , that no one can find out whom a special dna sequence is collected from , this paper get a new method ? savior , by improve dnala ( dna lattice anonymization ) , which is a method settling this question . savior replaces the multiple alignment in dnala with pairwise alignment between every tow sequences , and replaces the greedy algorithm in dnala with stochastic hill - climbing . for doing this , it can save the time for data pretreatment , and add the precision of classing
针对个人dna数据的隐私保护问题,即:如何保证无法将存储在数据库中的dna序列信息与其提供者的个人身份信息(如:姓名,身份证号码等)联系起来,本文对一种新近开发的隐私保护方法? dnala ( dnalatticeanonymization )进行了改进,在数据预处理阶段,用两两双序列比对代替了原算法中的多序列比对,在不降低处理精度的情况下减少了数据预处理所耗费的时间;用随机爬山法代替了原算法中的贪心策略,增加了算法后期处理的精度,从而形成了一种新的算法? savior 。
In the design of corpus , we carefully analyze the syllable distribution of corpus th - coss , then classify the prosodic characters of this corpus and present out the distribution of every prosodic character . based on prosodic character vector , we construct an error function which is used to select original corpus for simulation system , and show the distribution of prosodic characters for the original corpus . greedy algorithm and corpus self - adaptive process are expatiated to set theoretical foundation for text material search
在语料库分析与设计方面,首先统计th - coss语料库中音节分布情况,给出th - coss语料库韵律特征分类,并对每一种韵律特征进行统计,然后构造了一个基于韵律特征向量的误差函数,并采用该误差函数提取语料组成模拟系统的初始语料库,分析该库的韵律特征分布,最后阐述了greedy算法与语料自适应过程,为文本语料的搜索打下理论基础。
In the leach - new protocol , the mainly improvement of the leach protocol exhibits as follow : for the sake of balancing the network load , the network choose the clusters based on the residual energy ; we take multi - hop communication between sensors instead of single - hop communication , which results in the reduction of energy consumption of clusters ; the new protocol finds the path to the cluster head with the minimum cost , using an algorithm similar to flooding to propagate the cost information and greedy algorithm to find the lowest cost link ; the algorithm for assigning tdma time slot reduces overall delays of network
在leach - new协议中,对leach协议的改进主要体现在以下几个方面:根据节点剩余能量选择簇头,以平衡网络负载;节点间采用多跳路由,降低簇头能量消耗;节点根据能量消耗的代价来选择至簇头的路由,通过扩散算法来广播代价消息,采用贪婪算法来选择能量消耗最小的路径;采用tdma时隙分配算法减少网络时延。最后,利用ns2仿真软件进行验证。
