Correct image segmentation plays a major role in the realm of biomedical image processing by providing some typical practical assistance to the physicians. Such as it provide visual information to the general practitioner like diagnosis of disease and its advancement, anatomical construction and most importantly in surgical arrangement. Now a day’s Image processing is used to identify the brain tumor. According to the World Health Organization, every year more than 500,000 people undergo brain tumor treatment. A tumor is defined as a new growth which has the capability to attack the neighboring tissues which are placed at different locations. Also they vary in shape and sizes. Commonly there exist two types of drain tumor: First one is called …show more content…
Based on MRI technique, the study of the main cerebral tissues such as white matter, gray matter and CSF is carried out. In such studies, segmentation step is required whose aim is partitioning the intracranial volume into potentially overlapping parts such as WM, GM and CSF.MRI is one of the common ways to visualize brain structure. Automatic segmentation of MR images is very useful for research and clinical study of much neurological pathology. The MRI scan is more reliable than CT scan for diagnosis because it does not affect the human body as it does not use any kind of radiation. MRI shares a common advantage with CT of high spatial resolution images but without ionizing radiation exposure. It possesses good contrast resolution for different …show more content…
The domain of automated inspection for brain tumor is found to be populated mostly by level set image Segmentation. Level-set technique is a process that provide a bodywork for tracing the dynamic interfaces and its shapes. In this technique, the fluid boundaries are replicated, like constructing the flame front. In computer vision and pattern recognition the level set method (LSM) had been widely used for image segmentation. The potential to bring out the complex outline and to automatically control such topological changes is the greatest advantages of this technique. Some of the topological changes are splitting and merging. The LSM comes under the category ACMs (Active Contours Model) whose foundation is built on Eulerian framework. Eulerian framework is defined as representation of geometric pattern of the active contour rather than expressing in terms of parameters. A huge literature is devoted to brain segmentation from MRI data. In order to perform general image segmentation, Chang and Valentino uses the simulated charged fluid framework which is governed by Poisson’s equation as a deformable model. Later Chang et al. proposed the Charged Fluid Model (CFM), a new deformable model that extends and modifies the charged fluid framework for T2MRI brain tumor segmentation. Ho et al. introduce an improved method in which blobby-shaped brain tumors are
