Abstract
The brain is one of the largest and most complex organs in the human
body. Some abnormal and uncontrolled growth of tissue taking place in
human brain called “brain tumor”. The objective of biomedical image
processing is that the image will be enhanced to support doctors more
easily in diagnosing and treating. The detection of brain tumor can be
performed by using various image processing techniques like brain
Magnetic Resonance Imaging (MRI), Computer Tomography (CT), Positron
Emission Tomography(PET), Electroencephalography (EEG) etc. Among these
techniques the brain MRI is widely adopted in the world due to its
significant features. Its correct detection and identification at an
early stage is the only way to get cure. Brain tumor tissues may become
malignant (cancerous) if not diagnosed. This paper deals with the
various aspects of the brain tumor detection. The paper discusses the
significant researches which are meant for the brain tumor detection
through MRI quality enhancement.
