Abstract
Official abstract text for this publication.
A method and apparatus for simulating depth of field (DOF) in microscopic imaging, the method comprising computing a blur quantity for each pixel of an all-focus image, performing point spread function operations on one or more regions of the all-focus image, computing intermediate and normalized integral images on the regions and determining an output pixel for the each pixel based on the intermediate and normalized integral images.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for simulating depth of field (DOF) in microscopic imaging to approximate a sequence of images, the method comprising: computing a blur quantity for each pixel of an all-focus image; performing a set of operations comprising a box point spread function (PSF) operation twice on one or more regions of the all-focus image; computing an intermediate integral image and a normalized integral image on the regions; and determining each output pi…
