基于窗口模式的自动聚焦算法

随着数字智能化技术的不断成熟与提高，自动聚焦技术也日益完善并广泛应用。简单介绍了目前一些经典的图像清晰度评价函数，并提出一种改进的拉普拉斯算子的图像清晰度评价函数。该算法把整幅图像分成不同的窗口，提出一个新的概念——兴趣参数，并引入至不同窗口。经过与其它一些经典算法进行大量的实验研究对比，证明该算法在聚焦的适时性、灵敏性和准确性上都具有一定的优越性。

Autofocus algorithm based on window model

With the continuously maturity and improve of the digital intelligent technology, autofocus technology is also increasingly refined and widely applied.This paper briefly presents some of the classic image clarity evaluation function,and proposes an improved Laplacian operator image clarity evaluation function.This algorithm divides the whole image into different windows,and proposes a new concept—interest parameters and leads it into different windows.After contrasting with other classic algorithms by substantial experimental studies,we prove that the algorithm have some advantages in the focus of timeliness, sensitivity and accuracy.
