Brain Tumor Segmentation Methods: A Review

Abstract

— Brain tumour is an abnormal growth of the cells
inside the brain. Detecting Brain tumour takes special skills and
techniques because they are difficult to detect – especially in
early stages. The boundary of the tumour (i.e. the abnormality in
brain) in an MRI or different medical image can be traced using
image processing techniques. Segmentation is often essential as a
preliminary step for medical image analysis for diagnosis and
study of abnormality. The input image to the system is taken
either from the available data base or the real time image, So
that the presence of tumour in input image can be detected and
the area of the tumour can also be analysed. The paper is based
on the survey of different brain tumor detection techniques.
