The detection of malignant masses by non-linear multiscale analysis
INT CONGR SER 1119 (1996) 335-340
Abstract:
We report on the development of a new method for detecting automatically malignant masses in digitised mammograms, based on a novel non-linear method of multiscale analysis. We show that it is possible to detect > 85 percent of all malignant masses by this method, irrespective of their size, with a false-alarm rate that is close to acceptable for asymptomatic screening.The peculiar motions of early-type galaxies in two distant regions .1.
