K-means clustering for support construction in diffractive imaging

J Opt Soc Am A Opt Image Sci Vis. 2014 Mar 1;31(3):470-4. doi: 10.1364/JOSAA.31.000470.

Abstract

A method for constructing an object support based on K-means clustering of the object-intensity distribution is newly presented in diffractive imaging. This releases the adjustment of unknown parameters in the support construction, and it is well incorporated with the Gerchberg and Saxton diagram. A simple numerical simulation reveals that the proposed method is effective for dynamically constructing the support without an initial prior support.
