％％％ Demos for PUMA algorithms ％％％ We present four matlab demos for PUMA. demo1, demo2, demo3, and demo4 illustrate PUMA working with different parameters and with four different images. All you need to do is to run each of the demos. Please be sure that all the files are put on an accessible path for matlab. Notice that this code is intended for research purposes only.

EM算法用于高斯混合模型，实现数据的精确分类(The EM algorithm for Gaussian mixture model, the exact classification of the data)

1.对原图像高斯平滑 　　2.对高斯平滑后的图像进行sobel边缘检测。这里需要求横的和竖的还有联合的，所以一共三个需要sobel边缘检测图像。 　　3.对联合的sobel检测图像进行非极大抑制 　　4.连接边缘点并进行滞后阈值处理。 (1. Gaussian smoothing the original image 2. Gaussian smoothed image was sobel edge detection. Here and there on request transverse vertical joint, so a total of three required sobel edge detection image. 3. sobel joint detection image greatly inhibit non- 4. Connect the edge point and hysteresis thresholding.)

It can be used for backpropagation, perceptron

脉动风速时程的matlab功率谱估计，汉宁窗法(power spectrum)

说明：  用遗传算法求解函数最优值，收敛速度快且不易陷入局部最优值。遗传算法是经典算法，此程序适合初学者。(A Genetic Algorithm for the optimal value function, convergence is fast and easy to fall into local optimal value. Genetic algorithm is a classical algorithm, this program suitable for beginners.)
