Abstract

Due to the limited depth-of-field of optical lenses, it is difficult to get an image with all objects in focus. One way to overcome this problem is to take several images with different focus points and combine them into a single composite which contains all the regions full focused. This paper describes a pixel visibility based multifocus image fusion algorithm. For each pixel in the source multifocus images, the pixel visibility is calculated. The fusion procedure is performed by a selection mode according to the magnitude of pixel visibility. Experiments show that the proposed algorithm works well in multifocus image fusion.
