%X Image interpolation is an important problem when enlarging digital images.Using fractal method to enlarge images can get better visual quality by adding more details to the images, because fractals have infinite details.With the low convergent speed for iterative image interpolation, we developed two methods to accelerate the convergence. For the first one, according to the theory of cybernetics, we developed a comparator, the other one we named it“crossed iteration”. The experimental results of the two methods showed they were much in evidence to accelerate the convergence. At last, the benefits and the limitations of the two methods are also analyzed and discussed in this paper.
