Yonghua Xie · Journal of Qingdao University · 2002
Efficient encoding algorithm is the key for image to store and transmission.With analyzing the merit and disadvantage of basic fractal encoding algorithm,a new fractal encoding method based on wavelet transform is proposed.Through the algorithm,the image is firstly decomposed with two scale wavelet transform,then according to the likeness of structure between different level subband image,we apply the basic fractal coding to the decomposed high level subband image and construct the low level fractal codes with the high ones.The experiment results is sutisfuctory,especially in shortening the encoding time and improving the compression rate.
