基于多项式外推的Richardson-Lucy算法加速研究

提出一种新的可加速Richardson-Lucy(R-L)图像迭代恢复算法的方法。该方法基于阻尼R-L算法,通过存储阻尼R-L算法的前若干次(n次)迭代运算结果,利用多项式外推法分析这前n次迭代运算结果,并用一个多项式函数近似描述各结果之间的关系。通过该多项式的外推,预测以后的迭代结果,从而减少迭代运算的次数,取得了较好的加速效果。该方法可以实现几乎没有图像失真的复原,并能应用于其他类型的算法。

A New Venture Analysis Method and Its Application

The new venture analysis is the foundation of venture development. In this paper, 14 venture prototypes are proposed based on the attributes of venture.Then, a new venture analysis method is discussed by the way of matching the new venture with the corresponding prototype. Considering the fuzziness of human subjective grading, the L-R fuzzy numbers are used to express the variables and corresponding fuzzy algorithm are applied in analysis. At the end, an application example is applied to indicate the effectiveness of the method.
