Early detection of the brain tumor in the brain magnetic resonance imaging is important because physician needs to quantification and classify of the tumor and its area. The computer and image processing techniques can provide great help in analyzing the tumor area and its type by classification. On the other side, computer-aided detection (CAD) has been developing fast in the last two decades. The main idea of CAD is to assist radiologists in interpreting medical images by using dedicated computer systems to provide 'Accurate System'. Studies on CAD systems and technology show that CAD can...
