7. This method according to claim 6, wherein said identifying step comprises: performing a contrast versus background test to determine for each signal for which features are extracted, whether that signal corresponds to a false positive signal, and if so, removing from said second binary image that pixel identifying the location of said false positive signal by setting the value of that pixel in the second binary image to a predetermined value.
8. The method according to claim 7, wherein said identifying step further comprises: a step of counting the number of pixels exceeding a predetermined value in a kernel of a predetermined size scanned across the binary image remaining after said area versus contrast thresholding test and said contrast versus background thresholding test, and copying the contents of the said binary image that lay within the kernel to the corresponding locations in a third binary image whenever the contents of the kernel meet a predetermined grouping criteria based on said counting; and indicating locations of microcalcifications in said original radiographic image based on the locations of pixels having a predetermined value in said third binary image.
