Lung segmentation has been an active area of research to study the methods on effective segregation of lungs parenchyma. When the thoracic CT image is focused to investigate the lung conditions, there is no need to process the adjacent tissues of lungs. Therefore lung region can be extracted from the CT image and can provide as input to subsequent operations. Apparently lung segmentation can be considered as the prerequisite step to examine whether there are any lung nodules that can be benign or malignant. Several methods have been proposed. Conventional techniques deal with the pixel values and perform operations on those values. However the recent developments in the area of machine learning and deep learning have remarkable impact on the accuracy of separating the image into distinctive parts. The proposed work has presented two deep learning models for effectively segmenting the lung fields. The first one is fully convolutional network (FCN) and the second one is UNet. The FCN model has achieved the dice coefficient of 78.17% and UNet resulted in 98.13% dice coefficient. Therefore UNet has been an appropriate model for segmentation and showed better results compared to FCN.
