Chronic Obstructive Pulmonary Disease (COPD) is a major originate of chronic morbidity and mortality. The term COPD does not refer to a single disease but is an umbrella term for chronic lung diseases that irreversibly limits the flow of air in the lungs. CT imaging is able to perform in visualizing the effects of COPD. An advantage of CT over Lung Function Test (LFT) is that CT can differentiate between the different types of COPD, making it possible to classify the different subgroups of diseases. The below figure shows the difference in CT between lungs of a relatively healthy subject and that of a subject with severe emphysema.
The above figure shows severe emphysema of the lungs. Basically, Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to overinflation of alveoli (air sacs in the lung). In people with

HRCT images have been used for applications such as lung parenchyma density analysis airway analysis and disease detection.
In this research, lung HRCT images are used for nodule detection and analysis. Most of the CAD systems consist of two stages, the first of which is the lung segmentation, and the second is the characterization of disease pattern. This Lung Image Processing was done using manual lung segmentation. There are some disadvantages using manual lung segmentation that is giving below:
In Manual lung segmentation technique, the process such as lung boundary tracking, seed point allocation and lung anterior and posterior junction lines obtainment are manually processed. This process includes so many steps to find out the disease in the lungs and it will take much more time and there is no guarantee for accurate diagnosis.

In order to avoid this problem, I used the flood fill method with advanced features to get the accurate result of disease in the lungs. In this method, time consumption is also very
