Image Separation and Reconstruction Method from a Double Exposure

Abstract

A new method to separate and reconstruct the images in a double exposure is presented. First, the relationship is derived between the Fourier phase and the energy density spectrum of the first of two images in a double exposure film frame. By using this relationship, the phase of the first image can then be reconstructed in terms of its relevant energy density spectra. The two images can be completely separated once the density spectra of both are known. Simulation examples show that image separation and reconstruction can be successfully completed using this method.
