We're currently using a Chirp-Z based implementation (Tong and Cox, 1999) for rotation of astronomical images. I was wondering if there were any algorithms/implementations out there that could also be used to rotate images using FFTs, and were more accurate than the one we're using now. Perhaps any progress made in the past few years in the area?
