认 知 无 线 电 中 的 频 谱 检 测 技 术(cognitive radio detection)

时频分析工具——径向高斯核时频分布。为了在时频分布平面内不出现交叉项，则在模糊函数域内应有效去除互分量而仅保留自分量。设计一个与信号相匹配的核函数可以达到上述目的。基于信号的径向高斯核时频分布是一种比较理想的时频分布(Optimal radially Gaussian kernel time-frequency representation)

本程序实现多模态故障检测与故障诊断，用的方法是pca_GMM_FJ，对象为TE,GMM是用的FJ算法，效果很好(This procedure realize multimodal, fault detection and fault diagnosis method is pca_GMM_FJ, object for TE, GMM FJ algorithm is used, the effect is very good)

用形态学的方法求二值图像的周长，面积，圆形度，矩形度和伸长度( use morphological mathod to get the perimeter, area, circle, the rectangle and stretch the length of the binary image)

说明：  floy 算法实现寻找最短路径问题,类似的还有迪克斯屈拉算法(floy algorithm to find the shortest path problem, there is a similar pull algorithm Dix ​ ​ Qu)

使用迭代式阈值算法来提高图像对比度。可以指定某个色阶作为阈值，所有比阈值亮的像素转换为白色；而所有比阈值暗的像素转换为黑色。 (The use of iterative threshold algorithm to enhance image contrast. You can specify a color scale as the threshold, all pixels lighter than the threshold into white and all pixels darker than the threshold value is converted to black.)
