| Abstract(in English) | In this article, the authors report about a method for classifying pulmonary nodules in three-dimensional X-CT images and about image features used for the classification. The classification method firstly segments the nodules in given three-dimensional X-CT images and then extracts nine kinds of image features that are represented by a fifty-one vector, which is input to the classifier. Given 309 training images of pulmonary nodules with five-grade evaluations, the authors constructed the classifier using a kernel SVM. Its classification ratio was about 75%. The F-score of each of the image features was evaluated and was used for selecting ons that contributed the classification well. In this article, it is reported that which images features contributed to the classification and that how the classification performance changed with respect to the change of the number of the input image features. |
