Abstract: Heart tumors are abnormal growths that arise in the heart muscle, inner lining or surrounding pericardium. The prevalence is 0.0001-0.5{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} of the population. Currently, the superlative method to identify the presence of heart tumour is through MRI imaging by detecting abnormal morphological characteristics. However, the boundaries of different tissues in MRI heart images are almost similar and indistinct as the intensities of the tumour tissue and normal tissue. In present paper, the methods used to process the MRI image are contrast enhancement, color transformation and isolating the region of interest. The overall contrast of the MRI image was enhanced using exponential transformation. The grey scale image is converted to color image using color map ‘jet’. The region of interest is obtained from the color image using binary masking. Finally, the colored region of interest is superimposed on the original image, which improved the SNR differences at maximum 6.20 percentages.
