We describe a new algorithm for microcalcification segmentation in mammographic X ray images. The algorithm detectsmicrocalcifications in two steps. First, it removes background tissue witha multiscale morphological operation. Then, it applies entropy thresholding based on a 3 -dimensional co-occurrence matrix. Unlikeexisting methods, ours is fully automatic, parameter -free, and independent of local statistics. To test its efficacy, we applied it to images from the Mammographic Image Analysis… CONTINUE READING
