A new auto-focusing algorithm was proposed,and it adopted image squared-gradient function based on focus windows by comparing three favorable sharpness functions. Additionally,it presented mathematical model and experimental analysis and results.
通过分析比较3种聚焦效果较好的清晰度评价函数,提出了一种基于聚焦窗口模式的平方梯度函数作为聚焦评价函数,建立了评价函数的数学模型,并给出了实验分析和结果。
