| KRATKA VSEBINA | We apply the 2D wavelet transform (WTMM) method to perform a multifractal analysis of digitized mammograms. We show that normal regions display monofractal scaling properties as characterizedby the socalled Hurst exponentH = 0.3 +- 0.1 in fatty areas which look likeantipersistent self-similar random surfaces, while H = 0.65 +- 0.1 in denseareas which exibit long-range correlations and possibly multifractal scaling properties. We further demonstrate that the 2D WTMM method providesa very efficient way to detect tumors as well as microcalcifications (MC) which correspond to much stronger singularities than those involved in the background tissue roughness fluctuations. These preliminary results indicate that the texture discriminatory power of the 2D WTMM method may lead to significant improvementin computer-assisted diagnosis in digitized mammograms. |
