An advanced segmentation using bit-plane slicing technique in extraction of lungs region

This paper presents the new method for the segmentation of pulmonary parenchyma. The proposed method is based on the bit-plane slicing technique. The original image is binarized using the bit-plane technique and among the different images the best binarized image is chosen. After the image is binarized, the labeling is done and the area of each label is calculated from which we obtained the next level of binarized image. Then the boundary tracing algorithm is applied to get the binarized image. The following steps show the automatic extraction of lungs area and experimental results has proved it´s significant.
