burtReconStep --- one level reconstruction of a Burt pyramid
DESCRIPTION
The burtReconStep operator performs one iteration in the Burt reconstruction
process. The top port input image is the gaussian image for the previous
level, while the bottom port input image is the laplacian difference image
for the current level. The output is the gaussian image for the current
level. The filter parameter selects the type of gaussian filter to be applied.
Currently, the user cannot define his own filters. The effect of each filter
is described in the WIT filter library during the discussion of the gauss
operator. Care must be taken to insure that the filter used is the same one
that was used to generated the pyramid, or reconstruction will not be exact.
