This paper presents a method that can remove streaking noise better by means of directionfiltering based on two dimension Fourier transform.
利用二维傅里叶变换进行方向滤波,较好地消除了南极地区影像上的条带噪声。

This is, admittedly, a very crude filtering mechanism, and any real scene engine would likely have a range of variables that would affect the direction of a person through the scenario.
