OPERATOR
expand --- expand and filter an image
DESCRIPTION
The expand operator increases the size of an input image by inserting a new
row (column) of zero-valued pixels between each row (column) of the input
image. The resulting image is then filtered using the gaussian filter
specified by the filter parameter. The filters are described in detail in the
gauss operator within the pyramid library. If the 'None' option for filter
type is indicated then no filtering is performed. The outputWidth and
outputHeight parameters allow the user to specify the width and height of the
output image. However, the values input are verified to assure that the
resulting image will have an appropriate size. If the reduce operator is
applied to an image I(i) and used to create an image I(i-1), then the
output width and output height should be set to the dimensions of image
I(i).
