This paper presents the comparisons of five different undecimated filter banks used for microcalcifications detection. The microcalcifications appear as a small number of high intensity pixels compared with their neighbors. As microcalcifications are high frequency signals, detection can be carried out by decomposing the image in several frequency subbands and discarding the subband that carries the lowest frequencies (smoth signals). The reconstruction of the image contains only details of high frequencies. The results obtained show that there is no a substantial difference in the number of detected microcalcification among the several filter banks. Key-Words: Breast cancer, Microcalcifications Detection, Undecimated filter bank.
