In this paper, computer-aided detection of microcalcifications in mammograms using a nonlinear subband decomposition and outlier labeling is examined. The mammogram image is first decomposed into subimages using a nonlinear subband decomposition filter bank. A suitably identified subimage is divided into overlapping square regions in which skewness and kurtosis as measures of the asymmetry and impulsiveness of the distribution are estimated. A region with high positive skewness and kurtosis is marked as a region of interest. Finally, an outlier labeling method is used to find the locations of microcalcifications in these regions. Simulation studies are presented.EnglishCalcification (biochemistry)CommunicationCommunication systemsComputer aided diagnosisDigital image storageFilter banksImage communication systemsImage processingImaging systemsLabelingMammographyMotion compensationVisual communicationComputer-aided diagnosesLabeling methodsMicrocalcificationsOut-liersPicture archivingRegion of interestsSimulation studiesSubband decompositionsPicture archiving and communication systemsConference Paper10.1117/12.263303
