| Abstract(in English) | In the previous report, we have developed a process based on comparison of bilateral mammograms and confirmed its effectiveness. In this process, 93 kinds of features were calculated from the bilateral mammograms and subtraction values between the features were computed as proposed features, called subtraction features. A sub-optimal feature set was selected from 186 features which consisted of 93 original features and 93subtraction features in order to discriminate candidates corresponding to tumors from those corresponding to normal tissues. This paper describes results of increasing number of features to 955 by adding four kinds of images, such as differential images of original mammograms. In the discrimination experiment using 1,008 mammograms, it was confirmed that the number of false positives was less than one third of the previous number. |
