这是一个数格网论的MATLAB程序源码，它可以用来产生样本数据(This is a number grid on the MATLAB program source code, it can be used to produce sample data)

区域生长算法，一种传统的图像分割算法，用于图像分割。(region growing algorithm for image segmentation .it is a trditional image segmentatin algorithm.)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)
