Brain image enhancement -A survey

Brain image enhancement, Examination, Conception and investigation permit measurable exploration and conception of medical images of various modalities such as MEG, EEG, PET, MRI, CT or microscopy, to name a few. The basic purpose of enhancement operation is to analyze the brain images precisely in order to effectively diagnose and examine the diseases and problems. Brain imaging is a subfield of medical image processing. The field basically deals with handling the functions and actions taken in the brain. Brain imaging provides a way to investigate and determine brain related diseases in an efficient and effective manner. Enhancement of brain images is a vast field in dealing with these images. The basic objective of this study is to evaluate and discuss different techniques and approaches proposed in order to handle different brain imaging types. The paper provides a short overview of different methods presented in the prospect of brain image enhancement.
