Abstract: Segmentation of lungs from chest radiographs (CXRs) is an essential pre-processing step performed for disease detection. Numerous techniques were proposed by the researchers to segment lung regions from the chest x-rays. In the past three years, hybrid techniques and deep learning-based techniques were proposed to increase the accuracy of segmentation. In this paper a hybrid method is proposed and evaluated for segmentation of lungs using chan vese snake segmentation method and boundary maps. The proposed method is evaluated using the public JSRT database and Jaccard index of our method is 95.2%, which can be compared to those of other best in class strategies (95.7%). The calculation time of our technique is under 13 s for a 256 × 256 CXR when executed on a standard computer.
