Comparative Assessments of Contrast Enhancement Techniques in Brain MRI Images

Image processing plays a significant role in the medical field, particularly in medical imaging diagnostics, which is a growing and challenging area. Medical imaging is advantageous in diagnosis and early detection of many harmful diseases. One of such dangerous disease is a brain tumor medical imaging provides proper diagnosis of brain tumor. This paper will have an analysis of fundamental concepts as well as algorithms for brain MRI image processing. We have adhered several image processing steps on brain MRI images, conducting specific contrast enhancements and segmentation techniques, and evaluating every techniques performance in terms of evaluation parameters. The methods evaluated based on two measurement criteria, Peak Signal to Noise Ratio PSNR and Mean Square Error MSE , namely Contrast Stretching, Shock Filter, Histogram Equalization, Contrast Limited Adaptive Histogram Equalization CLAHE . This comparative analysis will be handy in identifying the best way for medical diagnosis, which would be the best method for providing better performance for brain MRI image analysis than others.
