1) 借助MATLAB画出误差性能曲面和误差性能曲面的等值曲线;
2) 写出最陡下降法, LMS算法的计算公式( );
3) 用MATLAB产生方差为0.05,均值为0白噪音S(n),并画出其中一次实现的波形图;
4) 根据2)中的公式,并利用3)中产生的S(n),在1)中的误差性能曲面的等值曲线上叠加画出采用最陡下降法, LMS法时H(n)的在叠代过程中的轨迹曲线。
5)用MATLAB计算并画出LMS法时 随时间n的变化曲线(对 应S(n)的某一次的一次实现)和e(n)波形;某一次实现的结果并不能从统计的角度反映实验的结果的正确性,为得到具有统计特性的实验结果,可用足够多次的实验结果的平均值作为实验的结果。用MATLAB计算并画出LMS法时J(n)的100次实验结果的平均值随时间n的变化曲线。
6)用MATLAB计算并在1)中的误差性能曲面的等值曲线上叠加画出LMS法时100次实验中的H(n)的平均值的轨迹曲线;
7)对以上实验结果给出一些你认为有价值的讨论。
(在实验中n=1,,…..N,N的取值根据实验情况确定,一般选取足够大以使算法达到基本收敛,本题作业以电子文档PDF格式提供)

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.)
