Both stopping criterions are based on the cross-entropy concept (ce), but the new criterion is simpler than ce criteria and can be realized with lower complexity.
这两种迭代终止准则都是基于互熵(CE)的概念，但是后一种比CE准则更简单，具有更低的计算复杂度。

This criterion includes a rule for selecting optimal stopping time so that the correlation of filtered image with noise is minimized.
This criterion can suppress the affection of minutiae to correlation coefficient and get a more accurate stopping time without knowing the noise variance.
