读入任意大小的图像，实现长和宽上的比例缩放,matlab 图像预处理处理中有用的小程序(imread a image and resize the size of the image)

通过滑动取相关值最后求最大值，找去最佳的样值抽样时刻，完成时间估计。这是一些基础的程序 (Through the sliding value of the final order to check the relevant maximum, to the best kind to find the value of sampling time, the estimated completion time. These are the basis of the procedures)

提出了一种递归方法，用来计算当室内反射光源视为Lambertian光源时，室内自由空间信道的冲击响应。(A recursive method for evaluating the impulse response of an indoor free-space optical channel with Lambertian reflectors.)

可用于分析混沌信号特性,很全面,希望站长能让更多的人能阅读到,谢谢!(Can be used to analyze the characteristics of chaotic signals, it is comprehensive, I hope regulators will allow more people to read, thank you!)

通过建立运动模糊数学模型, 进行了消除运动模糊的仿真实验, 维纳滤波恢复运动模糊图像效果较 好。在图像恢复技术中, 点扩展函数( PSF) 是影响图像恢复结果的关键因素, 所以常常利用先验知识和后验判 断方法估计PSF函数来恢复图像。实验表明在实际恢复过程中如果运动模糊图像混入了噪声, 必须考虑到信噪 比、噪声的自相关函数和原始图像的自相关函数对恢复后图像的影响。(Through the establishment of mathematical model of motion blur was conducted simulation experiments to eliminate motion blur, Wiener filter to restore motion-blurred image effect is good. In the image restoration technology, the point spread function (PSF) that affect the results of image restoration a key factor, so often used to determine a priori knowledge and a posteriori estimation PSF function to restore the image. Experimental results show that the actual recovery process if the motion-blurred images mixed with the noise, we must take into account the signal to noise ratio, the noise autocorrelation function and the autocorrelation function of the original image of the restored image effects.)
