代码说明:

提出了一种基于 Renyi 熵的阈值分割新方法。该方法首先计算代表目标和代表背景的熵值,然后求出两熵之和以及两熵之差的绝对值,最佳阈值对应于两者比值的最大值。Renyi 熵比传统的 Shannon 熵多了一个参数,此参数使得 Renyi 熵能够更灵活地处理多种类型的图像。按照本文方法进行实验,结果显示该算法比传统的 Shannon 熵方法更有效。

    NW小世界网络的构成原则为:从一个环状的规则网络开始,网络含有N个结点,每个结点向与它最近邻的K个结点连出K条边,并满足N>>K>>In(N)>>1。随后进行随机化加边,以概率p在随机选取的一对节点之间加上一条边。其中,任意两个不同的节点之间至多只能有一条边,并且每一个节点都不能有边与自身相连。改变p值可以实现从最近邻耦合网络(p=0)向全局耦合网络(p=1)转变。在p足够小和N足够大时,NW小世界模型本质上等同于WS小世界模型。 (NW constitutive principles of small-world networks: from the rules of a ring network, network with N nodes, each node is connected to the K node with its nearest neighbor K edges, and meet N > > K > > In (N) > > 1. Followed by randomization into the plus side, with probability p with an edge between a pair of nodes in a randomly selected. Wherein between any two different nodes at most only one edge, and each node can not have a side connected with itself. P value can be changed to achieve the transition from the nearest neighbor coupling network (p = 0) coupled to the global network (p = 1). When p is small enough and large enough N, NW small-world model is essentially the same as the WS small-world model.)

  • Calculate-Time-Interval
    main executing reference usage: usage_timeDifference.m Sample output: The time interval between earierTime [09-Sep-1900 09:09:18] and laterTime [31-Oct-2010 23:33:08] is 110 years, 79 days, 14 hours, 23 mins, 50.17 secs. The objective is to compute the time interval taking into account the leap days that are subsumed within the time interval. Note: The logic subsumes the time interval by yearEnd, monthEnd, dayEnd - timeEarlier (within that year) + time interval (excluding that 2 years) + timeLater - yearEnd, monthEnd, dayEnd (within that year) It differentiates the earlier time and later time, ie. timeDifference (earlierTime, laterTime) gives the same result as timeDifference (laterTime, earlierTime). leapDayHasPassed.m illustrates a possible approach to determine if a certain day of concern is already over at a given time. Caveat: does not include leap secs
