Abstract

Restoration of depth images obtained by serial slicing of the image volume, is complicated by the fact that one part of an opaque 3D object can partially block another part from the view of the imaging lens. This type of obscuration makes the point spread function (PSF) object dependent. We present a general algorithm that adapts a transparent PSF to represent the effects of the opaque or semi-transparent object. Examples of its application are given using simulated annealing and modified iterative backprojection to carry out the iterative restoration.
