独立分量分析中的ogwe算法代码 matlab 格式 希望对大家有用(independent component analysis algorithm code of ogwe hope Matlab format useful for all)

第一：边界加强，通过估计噪声和实际信号的比值，来确定各个尺度的细节系数，以达到噪声抑制和边界加强。第二，通过对小波分解的近似部分进行直方图均衡，达到加大整幅图片的对比度，而不太影响细节的目的。(First: to strengthen the border, through the estimates and the actual signal noise ratio, to determine the details of each scale factor, so as to achieve noise suppression and boundary strengthening. Secondly, the wavelet decomposition of the approximate portion of histogram equalization to increase the contrast of the whole images, and do not affect the details of the purpose.)

这是一个matlab编写的电离层误差图的程序。里边分别利用广播星历和模型修正进行了编程。(It is written in a matlab program ionospheric error plots. Inside were using broadcast ephemeris and model updating for the programming.)

说明：   MATLAB的NSGA改进后的算法(MATLAB' s NSGA improved algorithm)

用MATLAB编写的巴特沃斯低通滤波器，可运行，参数可变(MATLAB prepared bart wo low-pass filter, can run, parameters variable)

MATLAB RQA 对离散时间序列进行递归图分析然后再进行定量递归分析，是做混沌研究的一种重要方法！(MATLAB RQA recurrence plot analysis of discrete time series then recurrence quantification analysis is an important method to do chaotic research!)

Abstract—This paper investigates the performance of a 4-switch

Matlab programs: A pendulum is a weight suspended from a pivot so that it can swing freely. SNR-Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.

对图片进行gamma校正，可以对黑白图片进行比较好的gamma校正，对彩色图片有一定得校正功效！(On the picture for gamma correction, black-and-white picture can be a better gamma correction, color picture of a certain efficacy of a correction!)
