M. Scheibe. Square isometries as integral part of fractal transformation - An analysis. Frequenz, 51(5):168-170, 1997.
In block based methods of fractal image compression the domain-pool is frequently enlarged by using square isometries of image blocks. This does not result in higher performance of fractal codecs, as described in various works. The present paper analyses the position of isometries in fractal transformation. The influence of rotation angle of blocks to the approximation of image ranges is examined. The conclusion shows under which conditions the use of square isometries results in a better image coding performance.
