MRI Brain Image Enhancement Using an Improved Contrast Enhancement Method
The uncontrollable cells growth in the brain portion is the main reason for cancer deaths nowadays.
So, effective detection of brain tumors is more important in the medical field to analyze the tumor
portion. Detecting tumors prior and diagnosis of tumors can play a major role in preventing human
death due to brain tumors. To detect the tumor portion, many segmentation and classification
methods have been proposed. For the effect segmentation process, enhancing brain images is
necessary. In this present paper, Magnetic resonance imaging (MRI) brain images have been taken
as test images. The proposed enhancement method has two major phases. The first phase contains a
regularization process in two steps to equalize the test images' intensities, and the second phase
contains a mapping process of two steps to enhance the contrast of the image and remap their
intensity values to the natural dynamic range.
