Abstract(in English) In this paper, we show a fractal block compression method using the Wilcoxon signed-rank test. The fractal block coding method based on an iterated function system is in the compressing method which attracts attention as a unique technique from before. This technique can be expected in high coding efficiency, and is excellent in the point of independence resolution. On the other hand, the length of coding time may be pointed out as a problem. This is attributed in the searching time of the domain block in a range block. Then, we tried shortening of coding time by clustering a domain block. Although various clustering techniques were used by past researchers, we adopted the clustering using the Wilcoxon signed-rank test directly to the luminosity value of a picture. Consequently, without reducing the quality of a reproduction picture remarkably, it was succeeded in shortening of coding time.
