Abstract
Fractal image compression entails a computationally costly search for matching image blocks. It is proposed that a block be represented by i ts DCT coefficients, which may be made invariant to many of the usual block transforms. Owing to the energy packing properties of the DCT, t he efficiency of an existing multidimensional nearest neighbour search is improved.
