Separating tumor in MRI(Magnetic Resonance Image) brain images is a stimulating task,since there are variation of tumor shape,tumorsize and tumor location on the brain. The detection of tumor is still developing in medical field. This study targeted to extract the brain tumor from the brain images and execute the exact tumor location and its size. MRI scans images are widely used in medical research and also used to detect abnormalities in our body especially tumors. In this work,the process of image segmentation is performed by Morphological operation and threshold operation. Finally the result of the segmentation is tumor region and the size of the tumor. © 2016,International Journal of Pharmacy and Technology. All rights reserved.
