- 将原图像看做是自相关及其功率谱是各向同性的一阶马尔可夫过程,采用基于方向微分的运动模糊方向鉴别方法，对运动模糊图像进行方向性的高通滤波(方向微分),当滤波方向为运动模糊方向时 ,由于此方向模糊图像对应的高频成分最少,高通滤波(方向微分)使模糊图像能量损失最大,得到的微分图像灰度值（双线性插值）之和必然最小.所以方向微分得到的图像灰度值之和中的最小值对应的方向即为运动模糊的方向-The original image as is the autocorrelation and power spect

Improved_TV_restoration
- 分析了基于整体变分（total variation,TV）模型的图像修复算法,TV模型修复算法只使用各向异性扩散,TV模型各向异性扩散仅向图像边缘方向扩散,容易在平滑区域引入阶梯效应。提出了一种改进的图像修复算法,该算法同时结合了各向同性和各向异性扩散,利用区域频率差异实现了在不同的区域使用不同的迭代方程,有效避免了原始算法引入的阶梯效应,同时在平滑区域提高了迭代效率。Matlab环境下的仿真结果表明,改进算法的修复效果和峰值信噪比的计算结果均明显优于原始算法-Analysis based on
