Whole lung quantification results for comparing the conventional SVM to the proposed method. Each pixel was coded by the classification result, indicated by a semi-transparent color (normal, green; ground-glass opacity, yellow; reticular opacity, cyan; honeycombing, blue; emphysema, red; and consolidation, pink). a Original HRCT image (case 1), b drawing by an expert (case 1), c quantification results from the conventional SVM (case 1), d quantification results from the csSVM (case 1), e original HRCT image (case 2), f drawing by an expert (case 2), g quantification results from the conventional SVM (case 2), h quantification results from the csSVM (case 2), i original HRCT image (case 3), j drawing by an expert (case 3), k quantification results from the conventional SVM (case 3), l quantification results from the csSVM (case 3), m original HRCT image (case 4), n drawing by an expert (case 4), o quantification results from the conventional SVM (case 4), p quantification results from the csSVM (case 4)
