An online block algorithm for frequency domain blind deconvolution was proposed based on the complete mutual information gradient and the properties of the score function difference (SFD).
基于完全互信息梯度表达式及得分函数差分的性质，提出一种在线频域盲解卷积块算法。
The greater the vertical maximum gradient is, the more powerful its capability to block vertical heat diffusion from upper water layer to deep water layer.
温度垂直梯度越大，它在垂直方向上阻碍上层海水的热量往深层扩散的能力就越强。
To minimise the temperature gradient across the sample, the light aperture in the block is only2.5 mm?.

This new method mainly comprises three steps: firstly, normalize the point-gradient vectors and calculate the block-gradient vectors and the corresponding block-coherence;
最后采用基于迭代的方法，重新估计所有块梯度向量并将梯度向量场转化为方向场。
