gaussPyramid --- generate a gaussian pyramid
DESCRIPTION
The gaussPyramid operator generates a sequence of images corresponding to a
gaussian pyramid. Each image G(i) is a reduction of image G(i-1).
Notationally,
G[1] = input image
G[i] = reduce(G[i-1]) for i > 1.
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. The minsize parameter defines the minimum size that an image G(i)
can be before a reduce operation will not be performed and pyramid generation
will terminate.
