Abstract
A method for removing a virtual object from a digitized image comprises the steps of computing a point spread function of the intensities of an image, wherein a point spread function is a measure of the blurriness of said image, marking a plurality of points that represent an object of interest in the image, and subtracting the point spread function value from the intensity for each marked point, wherein the object of interest is removed from said image.

A method for identifying and removing a virtual object from a digitized image comprising the steps of:
- providing a digitized image comprising a plurality of intensities corresponding to a domain of points on a n-dimensional grid;
- computing a point spread function of the intensities of said image, wherein said point spread function is a measure of the blurriness of said image;
- marking a plurality of points that represent an object of interest in said image;
- and
- subtracting the point spread function value from the intensity for each marked point, wherein said object of interest is removed from said image.
A method for identifying a virtual object from a digitized image comprising the steps of:
- providing a digitized image comprising a plurality of intensities corresponding to a domain of points on a n-dimensional grid;
- and
- marking a plurality of points that represent an object of interest in said image;
- creating a fuzzy map for said object of interest, wherein said fuzzy map value for each point characterizes the degree to which said point is a member of said object of interest wherein the values of said fuzzy map range from 0.0 to 1.0, wherein a map value of 0.0 indicates that the point does not belong to said object of interest, while a map value of 1.0 indicates that said point completely belongs to said object of interest.
A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform the method steps for removing a virtual object from a digitized image, said method comprising the steps of:
- providing a digitized image comprising a plurality of intensities corresponding to a domain of points on a n-dimensional grid;
- computing a point spread function of the intensities of said image, wherein said point spread function is a measure of the blurriness of said image;
- marking a plurality of points that represent an object of interest in said image;
- and
- subtracting the point spread function value from the intensity for each marked point, wherein said object of interest is removed from said image.
