The traditional fractal image compression coding that was designed by Barnsley is to divide an image that wants to be coded, then fractal image compression coding is begun with a compression dictionary that is made up from the image. For this reason, the compression dictionary is always changeable. Firstly, this paper measures "Julia curves"with square patterns by many ways, then "Julia curves"of measurement apply to coding fractal image and eliminate the defect that fractal image compression coding depends on changeable code compression dictionary. In addition, this paper also builds a small common dictionary that applys to speeding up fractal image compression coding. The experimental results show that the "Julia curves"can collage fractal image to be encoded very well and has some fractal image merit decoding.
Key words： Julia curves; fractal; image coding; image compression dictionary; decoding
