Brain Tumor Detection from Pre-Processed MR Images using Segmentation Techniques
Sarbani Datta, Monisha Chakraborty · 2011
resonance imaging (MRI) has become a common way to study brain tumor. In this paper we pre-process the two- dimensional magnetic resonance images of brain and subsequently detect the tumor using edge detection technique and color based segmentation algorithm. Edge-based segmentation has been implemented using operators e.g. Sobel, Prewitt, Canny and Laplacian of Gaussian operators. The color- based segmentation method has been accomplished using K- means clustering algorithm. The color-based segmentation carefully selects the tumor from the pre-processed image as a clustering feature. The present work demonstrates that the method can successfully detect the brain tumor and thereby help the doctors for analyzing tumor size and region. The algorithms have been developed on MATLAB version 7.6.0 (R2008a) platform.
