Abstract: A Computer-Aided Diagnosis (CAD) system is required to precisely detect diseases from the given chest x-ray. Lung segmentation is the basic step performed in the detection of diseases from the chest x-ray. In this paper, we use euler number-based thresholding method for lung region segmentation from CXR images. Morphological operations and greedy snakes are used to improve the accuracy of segmentation. The proposed method is experimented on two datasets: JRST and India. JRST contains 247 chest X- rays and India set contains 100 chest X-rays. An overall accuracy of 96.25% was achieved. The proposed method is compared with state of art methods and it gives high accuracy and high performance.
