产生一个验证码，有四个数字组成，有噪音，椒盐噪声等(failed to translate)

从matlab矩阵生成stl格式文件，适用于多孔介质图形生成(Generating STL format files from MATLAB matrix)

说明：  这个代码是基于贝叶斯的阈值分割,很有用的(This code is based on the Bayesian threshold segmentation, very useful)

加权中值滤波,用于图像增强,只用于超声图像,对超声图像去噪有很好的效果(Weighted median filter is used for image enhancement, only for ultrasonic image, has the very good effect on the ultrasonic image denoising)

说明：  通过偏振进行图像处理和图像复原，利用大气光和物体反射光的光学模型进行复原(Image processing and restoration are carried out by polarization, and restoration is carried out by optical model of atmospheric light and object reflected light)

实现了一个小球自由落体碰撞地面并弹跳的过程，设置了一个碰撞衰减系数c,可以自己调整衰减速度。(The process of collision and bounce of a small sphere falling freely on the ground is realized. A collision attenuation coefficient C is set to adjust the attenuation speed by itself.)
