Wavelet analysis of tree developments

摘要

In this paper two dimensional wavelet transformation of tree patterns are carried out with Haar function and Meyer function as analyzing wavelet. The results obtained in this work are as follows.rn(1) The scale parameter h implies that the width of analyzing, and When h is large the analysis is carried out for wide area in x-y coordinate.rn(2) The area which wavelet coefficients exist corresponds to the area of tree developments.rn(3) The coefficients analyzed by Haar function is a little bit different from that of Meyer function.rn(4) The wavelet coefficients is large in the boundary of the tree patterns.
