System and method for auto-focusing an image

Abstract

A method and system for auto-focusing is disclosed where the number of the fractal pixels having a fractal dimension within a predetermined range is determined. The focused image is determined by adjusting the image to maximize the fractal pixel count. Alternatively, the focused image may be selected from a set of images, the image having the largest fractal pixel count selected as the focused image.

1 . A computer program embodied in a computer readable medium for automatically selecting an in-focus image of an object, comprising:
 obtaining a set of image slices of an object at different focal distances;   determining a fractal pixel count of each image slice; and   selecting the image slice of the object displaying the highest pixel count as the in-focus image of the object.
