To accelerate decoding fractal-coded images, researchers have actively investigated methods for deriving dependency regions. This paper describes a novel approach to expanding dependency regions for fast fractal image decoding. Our approach carefully identifies and encodes data dependency at encoding time in such a way that the decoder guarantees to get the dependency regions and further expands the dependency regions effectively. The experimental results show our approach improves the efficiency of the fractal decoding process significantly.
