Author: Xianju Wang Summary: 2 Dimensional Spectral Estimation MATLAB Release: R12 Description: Estimating the power spectrum associated with a random process is desirable in many applications. This package includes four important 2-D spectral estimation methods.(Periodogram, Autorrelation Method, Covariance Method, Modified Covariance Method).(Author : Xianju Wang Summary : 2 Dimensional Spectral Estimation MATLAB Rele ase : R12 Description : Estimating the power spectrum associated with a random process is desirable in many applicati ons.

Graph-Based Segmentation 是经典的图像分割算法，该算法是基于图的 贪心聚类 算法，实现简单，速度比较快，精度也还行。(Graph based Segmentation is a classical image Segmentation algorithms, the algorithm is Based on the figure of greedy clustering algorithm, speed is faster, and easy to implement precision is also ok.)

独立变量分析，主成分分析，盲源分离经典算法，屡试不爽(ICA BSS)

QPSK星座图，信噪比为5dB，10dB(QPSK constellation, the signal-to-noise ratio is 5dB, 10dB)

将随机数字信号进行16-QASK调制，使用升余弦滤波器模拟具有噪声的信道，绘制眼图，并采用眼图寻找最佳判决时间(The random 16-QASK digital signal modulation, the use of raised cosine filter simulation of the channel noise and draw the eye diagram, using the eye diagram to find the best judgments of time)
