A method and apparatus for processing an image by adding a border to the image, where said border has a width that is proportional to the extent of a filter used during image processing. Specifically, the processing reduces an image to produce an image pyramid and expands an image pyramid to produce an image. At each pass through the reduction or expansion process, the border is added to the image being processed, where the border has a width that is at least as large as an extent of a filter used in the reduction or expansion process.
