Contrast Enhancement of brain MRI images using histogram based techniques

Abstract: MRI is an advanced medical imaging technique used to produce high quality images of human body and different parts. It gives detail information to analyse the diseases. Medical image processing plays important role to give information in more extent for such advance images. Original MRI images are generally having low contrast. It is difficult for doctors to analyse them. By increasing the contrast of an image, it will be easy for analysing because of detailed information. This increase in contrast can be done by number of ways in image processing. This paper compares different methods of enhancement of brain MRI using histogram based techniques.
