Abstract
In designing a computer-aided diagnosis (CAD) system for classifying diffuse lung opacities in thin-section computed tomography (HRCT) images, the computational cost is an important factor. In this paper, the feature selection methods for reducing the dimensionality of the combined feature vector are investigated.
