Abstract
The presented method of extraction of the exact shape of the microcalcifications (MCs) is based on the watershed segmentation (WS) and region merging. Assuming that the locations of the MCs are known, we use two kinds of markers for the WS: the internal marker indicating the interior of the MC, and the external marker separating the MCs. Carrying out the WS in the area between these two markers we obtain a limited number of regions. These regions are merged into a mask of an MC by maximization of the average contrast between the mask and its surroundings. The obtained shapes of the masks agree with human intuition and can be used for the classification of MCs as to their malignancy.
