Lung cancer is one of the most prevalent diseases in the world. Recently, PNGGOs (Pure nodular ground-glass opacity) have been reported to increasing aspect for all CT-detected pulmonary nodules. Moreover, the malignancy rate of PNGGOs is a considerable proportion of benign diseases. In this reason, we have studied about automatic classification of malignant PNGGOs following below step. Segmentation of PNGGOs is performed by threshold technique. After that, Euclidean distance between the histogram based statistical features and region based features of benign and malignant GGO is extracted. Finally, K-means classifier is applied. Experiment is performed employing 12 CT image sets and 91.67% of recognition rates were achieved. |
