Abstract

A simple algorithm is proposed for synthesis of a pan-focused picture from the focused segments of partially-focused pictures taken along the depth. The procedure of discrimination of the focused segments consists of two steps. In the first step the local maximum of contrast is detected by applying a 3×3 differential mask. In the second step the maximum of intensity along the depth is detected. By arranging the intensity according to resulting map of the positions infocus a pan-focused picture is obtained. The whole process of obtaining a pan-focused picture from 60 frame images requires 60 minutes with a personal computer.
