Description: 2、图像增强：
图像增强也称为图像锐化，其目的是为了加强图像中的轮廓边缘等细节信息。
与图像平滑一样，也可分别在空域和频域进行图像增强。
在空域中进行图像锐化：
将原图像与 相减可以得到经过锐化处理的图像g(i,j)，即：
g(i,j)= f(i,j)-
= f(i,j)-α[f(i+1,j)+ f(i-1,j)+ f(i,j+1)+ f(i,j-1)-4 f(i,j)]
= f(i,j)+4α[f(i,j)- ]
这里，α为可选择的用于控制锐化程度的因子，其中,1/4 是被锐化处理点的周围4邻点之灰度的平均值。
原图像经过锐化处理后，灰度变化较平坦的区域，变化不大，而包括轮廓点在内的灰度变化较剧烈的区域，灰度差别加大，即图像细节得到增强。
也可以在频域进行图像的锐化处理。-err

Description: This GUI can be used by entering nu at the MATLAB command prompt. The user can either select a function (f(x)) of their choice or a statistical distribution probability distribution function to plot over a user defined range. The function s integral can be evaluated over a user defined range by using: The composite trapezium, simpsons and gauss-legendre rules. This is useful for calculating accurate probabilities that one might see in statistical tables.

Description: 摘 要 盲图像恢复的主要困难是信息不足，而为了恢复图像和确定点扩散函数需要适当的先验知识。解决这个问题的法、 法以及正则化方法等。但是这些方法的计算量都太大，针对上述方法的不足，文章提出了一种恢复图方法有图像的新算法，它通过恢复残差的最小化和后验概率的最大化来估计参数和恢复图像。其中，巧妙地利用了最陡梯度法和
共轭梯度法的迭代求解。对由于运动造成的模糊图像，可以明显地改善图像的质量，实验结果证明，在对模糊操作没有严格限制的情况下，仍可得到较好的恢复图像。-：
