ABSTRACT:
A circuit for filtering an input digital image comprising: first storage apparatus for storing the input digital image; apparatus for retrieving the input digital image from the first storage apparatus and generating a first resized digital image of reduced spatial frequency relative to the input digital image and being of smaller size than the input digital image; second storage apparatus for storing the first resized digital image; apparatus for retrieving the first resized digital image from the second storage apparatus and generating a second resized digital image of equal size to the input digital image, wherein the second resized digital image is a low-pass filtered version of the input digital image due to the reduced spatial frequency of the first resized digital image; and third storage apparatus for storing the second resized digital image.
