Extraction of Brain Tumour from MRI Images using Marker-Based Watershed Transform

Abstract

A brain tumor is an abnormal tissue growth in the brain in which cells grow and multiply uncontrollably. The main aim of our task is to identify brain tumor from a particular MRI image and to extract the tumor region. The proposed method uses various digital image processing techniques such as noise removal, Otsu's thresholding, morphological operations etc. This paper focuses on the use of marker-based watershed transform for segmentation, to get near about accurate results.
