A Survey on Extraction of Brain Tumor using Image Processing Techniques

Abstract

Image processing techniques are allowing earlier detection of abnormalities and treatment
monitoring, because the time is a very important factor in tumor treatment. Image processing
techniques are used for the easy detection of Brain tumor. Brain tumor analysis is made by
doctor but its grading gives different conclusions which may vary from one doctor to another.
Different types of methods like CT scan, x-ray and MRI can be used. Out of all the available
methods, MRI is the most dependable and harmless method that can be used. MRI can be
then processed and segmented for detection of tumor. This process includes various
techniques which can be put upon. This research considers the use of several techniques
proposed by professionals and reappraisal on these methods.
