| Outline of Final Research Achievements |
The classification of diffuse lung opacities in thin-section computed tomography(HRCT) images is an important step for developing a computer-aided diagnosis(CAD) system. In designing the CAD system for classifying diffuse lung opacities in HRCT images, a local histogram and a local slice feature vector has been proposed and shown to be effective, respectively. We have also developed a combined feature vector of a local histogram and a local slice feature vectors in order to improve the diffuse lung opacities classification. Furthermore, we have examined the combined feature vector with normalization techniques. In effectively classifying diffuse lung opacities in HRCT images, we recommend to use the localization of the feature vector.
