Paper Abstract

Depth of field (DOF) is still a limitation in the acquisition of sharp images. Since DOF depends on the optical system, a shallow DOF is common in macro-photography and microscopy. In this work, we propose a post-processing method to improve an all-in-focus algorithm based on a linear system. Using a multi-focus stack we extract a focused object of interest. Finally, we synthesize a single image with extended DOF including occlusions using a-priori information of the objects of the acquired scene. We present theory and experimental results to show the performance of the proposed method using real images captured with a fixed camera.
