Paper Abstract

The methods based on spatial and frequency domain processing for resizing the reconstructed image of digital hologram are studied. The first kind of methods for resizing reconstructed image is to resample the hologram. The reconstructed image is reduced by up-sampling or interpolating the hologram and the reconstructed image is magnified by down-sampling hologram. But its viewing angle is reduced. An approach is proposed to preserve the viewing angle. The second kind of method for resizing reconstructed image is to resample selected region in frequency domain of hologram. The reconstructed image is resized by this method without changing its viewing angle.
