A One-Pass Version of Two-Pass Image Resampling
Nelson Max · Journal of Graphics Tools · 1998
The intermediate storage and memory access for the first-pass output of the Catmull-Smith two-pass image resampling are eliminated by feeding output directly to the second pass as soon as it is computed. The algorithm reads input and intermediate data sequentially, so that it is suitable for efficient hardware or software implementation on modern, cache-based computers.
