rarely achieved, and the z dimension is much thicker. In the following sections
we describe the methods for deblurring and restoration of images obtained via
optical sectioning. Then we describe some 3-D image processing, analysis, and
display techniques.
14.4 Image Restoration and
Deblurring
The aim of image restoration is to bring an image as close as possible to what it
would have been if it had been recorded without degradation. Typically, restor-
ation encompasses the processes of noise removal and image deblurring via
deconvolution. The primary task of deblurring is to remove or reduce the out-
of-focus haze arising from objects located above and below the plane of focus.
In order to achieve this, the deconvolution process estimates the amount ...
