| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we examine various voxel classification methods for auto-extracting ground glass opacity (GGO) nodule candidates. Classifiers evaluating experimentally are two types of one-class classifier (threshold functions of a Mahalanobis distance and a norm of residue by embedding in a manifold trained by Isomap), and two kinds of two-class classifier (a threshold function of Mahalanobis distance ratio and a classifier ensemble trained by AdaBoost). In addition to evaluate the classifiers individually, four cascade classifiers each of which are combination of an initial rejection by the one-class classifier and a following classification by the two-class classifier are also validated experimentally. The evaluation results show the cascade classifier has a potential for providing the voxel classification results to extract GGO nodule candidates with high performance. | |
