这是matlab中常用的快捷键，可以使你使用matlab更顺手。(This is the common shortcut keys of matlab.It can make you use matlab better.)

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。(constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.)

This program segment the tumor present in brain image. Sine brain symmetric about central axis brain is divided into 2 equal halves about the central axis.Histogram of both the part is taken. based on the histogram threshold is set.Result of segmentation is the segmented tumor.
