Abstract
We show that a biorthogonal spline wavelet closely approximates the pre-whitening matched filter for detecting microcalcifications in digitized mammograms. The wavelet transform acts like a bank of such detectors operating at multiple scales. Object shape computed from zero-crossings produced by the same wavelet helps to reduce false alarms. Detection performance is tested on 40 mammograms digitized at 100 /spl mu/m resolution.Keywords
