In optical image processing, selective edge enhancement is important when it is preferable to emphasize some edges of an object more than others. We propose a new method for selective edge enhancement of amplitude objects using the anisotropic vortex phase mask by introducing anisotropy in a conventional vortex mask with the help of the sine function. The anisotropy is capable of edge enhancement in the selective region and in the required direction by changing the power and offset angle, respectively, of the sine function.
在光学图像处理中，当希望更突出物体的某些边缘而不是其他边缘时，选择性边缘增强很重要。我们提出了一种使用各向异性涡旋相位掩模对振幅物体进行选择性边缘增强的新方法，该方法借助正弦函数在传统涡旋掩模中引入各向异性。通过分别改变正弦函数的幂和偏移角度，这种各向异性能够在选定区域和所需方向上实现边缘增强。
