A hierarchical image model is used for segmenting chest radiographs. First, we use an active shape model (ASM) to segment the lungs. Then, using the segmented lung, we initialize the segmentation of the inter-costal parenchyma regions, using another four ASM models. We have found that the overall segmentation system is robust, and has been able to adapt to variations in lung height and in the number of inter-costal parenchyma regions.
