Review of brain tumor classification by texture base optimize features

Generally, experts perform certain evaluation procedures over these medical images which leads to operational errors. These errors require huge amount of time for making evaluations. MR images are qualitatively and quantitatively analysed by experts as per their experience. But it is limited to human eye, which is restricted up to 8 bits of grey level. Edge detection has its own reputation in image processing. Region boundaries and edges are quite similar, there is an iterative alteration of intensity at the region boundaries. Edge detection techniques recognized the edges which are non-continuous. There is a requirement of closed region boundaries, to segment an object from an image. The expected edges are the boundaries which lie between objects. It means edge based detection supports image segmentation.
