fsdStep --- generate a new level in a FSD pyramid
DESCRIPTION
The fsdStep operator performs one iteration in the generation of a FSD pyramid
(see fsd ). The image output on the top port is equivalent to applying the
reduce operator to the input image. The image output on the middle port is
the difference between the input image and the filtered version of that
image. The bottom output port is a flag which is set to 1 if this last
iteration is the final step in a FSD pyramid generation. The flag is 0
otherwise. The final iteration occurs when the output image size is less than
minimum size in at least one dimension. The filter parameter specifies the
type of gaussian filter used during image reduction. The filters correspond to
those provided by the gauss operator within the filter library. The minsize
parameter denotes the minimum size of image that will be accepted as input
to the operator.
