Detection of clustered microcalcifications with SUSAN edge detector, adaptive contrast thresholding and spatial filters

Abstract

Clustered microcalcifications (MCs) are detected in digital mammograms using SUSAN edge detector and adaptive contrast thresholding technique. MC clusters are found using spatial filters. Based on that a computer aided diagnostic prompting system is developed which achieves 97.4 % of true positive clusters at very low false positive rates according to the trial of 100 patches with the signs of both benign and malignant nature taken from the DDSM database mammograms © 2008 Springer-Verlag Berlin Heidelberg.
