Abstract

A method is proposed for depth field reconstruction from a set of layers – microscopic images obtained with different focus length. The method is based on local value estimation of gradient amplitude field dispersion. Analysis of its distribution in different layers leads to estimation of distance to the corresponding scene point and to separation of object and background. Visualization system of reconstructed depth field and sharp image is implemented.


Keywords: shape from focus, microscopic images, local dispersion.
