Taper discontinuities along image edges
The output image
J is the weighted sum of the original image
I and its blurred version. The weighting array, determined
by the autocorrelation function of
J equal to
I in its central region,
and equal to the blurred version of
I near the edges.

I — Input image
Input image, specified as a numeric array.
PSF — Point spread function
Point spread function, specified as a numeric array. The size of the
PSF cannot exceed half of the image size in any
