The respiratory system of lungs contains airway trees. The detection and segmentation of airways is a challenging job due to noise, volume effect and non-uniform intensity. We present a novel automatic method of lung segmentation and airway detection using morphological operations. Optimal thresholding combined with connected component analysis gives good results for lung segmentation. We describe a quick method of airway detection with grayscale reconstruction performed on four-connected low-pass filtered image. The results are quite satisfactory with some error due to non-uniform intensity and volume effect in the CT image.
