基于差分进化算法的查找表逆半调模板选择

LUT Inverse Halftoning Template Selection Based on Differential Evolution Algorithm

为提高图像逆半调技术中传统查找表法的模板对逆半调图像的质量和效果,提出了一种基于差分进化算法求取图像逆半调技术中查找表最优模板选择的方法。实验表明本文方法寻得的模板具有全局最优性,求得的最佳模板与其它算法相同,但是在收敛速度方面优于其它全局搜索算法。

To improve the inverse halftoning image quality and effect of traditional LUT template, proposed optimal LUT template selection based on differential evolution algorithm. Experimental results show that the template prepared by the method has global optimality, the best template is same with the template of other algorithms, and it is superior to other global search algorithms in the convergence speed.
