Abstract
We present an automatic system for detecting diffuse abnormalities in chest radiographs. The system starts with segmentation, subdivides the lung fields in smaller, overlapping regions and extract texture features from each ROI. Using these features, the probability that each ROI contains abnormalities is estimated with a k-nearest-neighbour classifier. The classification of all regions is pooled into an overall abnormality indicator. Evaluation on databases containing cases of interstitial disease and tuberculosis shows promising results. Directions for further research are briefly discussed.
