在图像处理中经常涉及分类，多次有用到非参数估计。本程序用Parzen窗来估计，用随机高斯函数来作计策信号.-in image processing involves classification, the many useful to the non - parametric estimation. The procedure used to estimate Parzen window, using random Gaussian function to signal for the ploy

模式识别的分类函数，包括PCA，风险贝叶斯，最小误差贝叶斯，parzen窗函数等等。-Pattern recognition classification functions, including PCA, risk Bayesian minimum error the Bayesian, parzen window function, and so on.

Multispectral remotely sensing imagery with high spatial resolution, such as QuickBird, IKONOS satellite imagery or Aerial imagery, especially in urban scenes, often perform spectral variations and rich details within a category, resulting in
