Bounding box based automatic segmentation of brain tumors using random walker and active contours from brain MRI

This paper reveals a computer aided system aimed at automatically segmenting brain tumors from MRI images is proposed, using bounding box-Active contour and Random walker algorithm. This method performs fast and accurate segmentation results by segmenting the most dissimilar regions of a tumor image. This paper overviews the benefits of automatic segmentation than the manual segmentation algorithms and we are proving that this algorithm is better than most of the segmentation.
