摘要：Brain cancer can be counted among the most deadly and intractable diseases. Tumors may be embedded in regions of the brain that are critical to orchestrating the body’s vital functions, while they shed cells to invade other parts of the brain, forming more tumors too small to detect using conventional imaging techniques. Brain cancer’s location and ability to spread quickly makes treatment with surgery or radiation like fighting an enemy hiding out among minefields and caves. Boundary detection in MRI with brain tumor is an important image processing technique applied in Radiology. The non-homogeneities density tissue of the brain with tumor can result in achieving the inaccurate location in any boundary detection algorithms. In this paper, we propose a new approach to detect the boundary of brain tumor based on the In this research paper we have proposed homogeneity enhancement process for brain image. This is followed by edge detection and finally obtaining the boundary by using Border Boundary Enhancement Algorithm. This composite method have been implemented and applied to brain database. The experimental results indicate that the boundary regions were extracted accurately characterize the corresponding ground truth images.
