众所周知,线性正核的迭代卷积在很方便的情况下会收敛到高斯函数。因此,信号或图像的所有迭代线性平滑方法归结为对热方程信号的应用。在这篇综述中,我们解释了如何通过对比度不变的单调算子对图像迭代平滑进行类似的分析。特别地,我们证明了所有迭代仿射和对比度不变的单调算子等价于唯一的仿射不变曲率运动。我们还证明了在非常广泛的条件下,加权中值滤波等价于平均曲率运动方程。
It is well known that a conveniently rescaled iterated convo- lution of a linear positive kernel converges to a Gaussian. Therefore, all iterative linear smoothing methods of a signal or an image boils down to the application to the signal of the Heat Equation. In this survey, we explain how a similar analysis can be performed for image iterative smoothing by contrast invariant monotone operators. In particular, we prove that all iterated affine and contrast invariant monotone opera- tors are equivalent to the unique affine invariant curvature motion. We also prove that under very broad conditions, weighted median filters are equivalent to the Mean Curvature Motion Equation.
