- 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

edges-master
- 边缘检测算子 图像边缘信息主要集中在高频段,通常说图像锐化或检测边缘,实质就是高频滤波。我们知道微分运算是求信号的变化率,具有加强高频分量的作用。在空域运算中来说,对图像的锐化就是计算微分。由于数字图像的离散信号,微分运算就变成计算差分或梯度。图像处理中有多种边缘检测(梯度)算子,常用的包括普通一阶差分,Robert算子(交叉差分),Sobel算子等等,是基于寻找梯度强度。拉普拉斯算子(二阶差分)是基于过零点检测。通过计算梯度,设置阀值,得到边缘图像。(The image edge infor
