Classification results of three emphysematous samples with each healthy sample. Multimodal projections of three healthy lung samples (normal1, normal2, normal3) and three emphysematous lung samples (emphysema1, emphysema2, emphysema3). To visualize the apparent differentiation of healthy and emphysematous lungs from the scatter plot, we propose using the threshold values produced by linear discriminant analysis, and the threshold values are displayed in jet colors, where higher values (yellow, red) correspond to lower scattering and thus larger mean alveoli diameter. The (A),(B),(C) show that the diseased regions of the same emphysematous lung sample have the same varying tendency under different healthy sample.
