morse
这是一个莫斯密码程序，可以方便进行莫斯变换和逆变换。
快和小伙伴们用密码通信吧。
( This is a Moss password program that can facilitate Moss transform and inverse transform.
Fast and small partners to communicate it with a password.)

isi_distribution_fit
he rational is simply to fit a mathematical model to the
ISI distribution that includes a component to model the
refractory period. If a neuron is well isolated, it must
exhibit some refractory period. If instead, it is multi-
unit, then it will exhibit instead something similar to
a poisson process in which there is no refractory period,
or at least large probability of inter-spike intervals
at the shortest intervals.

SVD_DWTimage
说明： 提出了一种新的基于离散小波变换(DWT)与奇异值分解(SVD)相结合的数字图像水印算法。该算法将原始图像作小波分解并将小波分解得到的低频子带进行分块，对每一块进行奇异值分解后，选取每块中最大的奇异值通过量化的方法嵌入经过Arnold置乱后水印信息。(A new wavelet transform based on discrete (DWT) and Singular Value Decomposition (SVD) combination of digital image watermarking algorithm. The algorithm for wavelet decomposition of the original image and wavelet decomposition low-frequency sub-band are divided into blocks, each a singular value decomposition, the selection of each block by the largest singular value methods to quantify Arnold scrambled after embedding the watermark .)
