Computer aided lung cancer detection system

Lung cancer is one of the most common types of cancer all over the world. The main cause of lung cancer is smoking. Accurate detection of lung cancer can increase the survival rate from cancer. A good lung cancer detection system will detect the tumor accurately. Computed Tomography (CT) images are usually used for detecting the cancer. The different stages in a Computer Aided Lung cancer detection system are Enhancement, Segmentation and Feature extraction. There are different techniques for performing these stages. These different techniques have been explained in detail.
