In this paper, a multi focus image fusion algorithm is proposed which takes features of human vision system (HVS) into account.

本文提出了一种考虑人眼视觉系统特性的多聚焦图像融合算法。

The wavelet has the good multi-resolution decomposition features, which both have a significant compression of image data, but also retain most of the information of an image.

而小波变换多分辨率分解的优良特性，既能大幅度的压缩图像数据，又能很好的保留图像的绝大部分的信息。

First, this paper st udies those visual features which have be en usually implemented in image correspondence including multi-scale features.
