中文说明：提出一种基于空间域的多聚焦图像融合技术：首先计算点分布函数（PSF），然后利用PSF模糊源图像，最后通过组合原图像中较为清晰的像素点来生成全聚焦图像。
English Description：
A spatial domain based multi focus image fusion technology: first compute the distribution function (PSF), then the PSF of the blurred image source, finally through the combination of original image clearer pixels to generate an all in focus image is proposed.
