| Research Abstract |
It is important for reading mammograms to compare right and left breast tissues. But, right and left mammograms were asymmetry. In this study, both mammograms were aligned automatically by both nipples, which were detected automatically. And then automatic mass detection algorithm of computer-aided diagnosis system was improved by a feature, which was that normal breast tissues on both mammograms were similar. Specifically, the similarity of both mammograms was analyzed by using correlations, the average differential densities on both images, he higher order local autocorrelation feature.
