The convergence of fractal operator F used in image compression is investigated by analysis of block influence graph and pixel influence graph. The graph stability condition in block influence graph implies eventual contractivity condition which is sufficient for the operator iteration convergence. The graph stability condition in pixel influence graph appears to be sufficient and necessary for convergence of selecting fractal operators.
