Low contrast of Magnetic Resonance(MR)images limits the visibility of subtle structures and adversely affects the outcome of both subjective and automated ***-of-the-art contrast boosting techniques intolerably alter inherent features of MR *** changes in brightness features,induced by post-processing are not appreciated in medical imaging as the grey level values have certain diagnostic *** overcome these issues this paper proposes an algorithm that enhance the contrast of MR images while preserving the underlying features as *** method termed as Power-law and Logarithmic Modification-based Histogram Equalization(PLMHE)partitions the histogram of the image into two sub histograms after a power-law transformation and a log *** a modification intended for improving the dispersion of the sub-histograms and subsequent normalization,cumulative histograms are *** grey level values are computed from the resultant cumulative *** performance of the PLMHE algorithm is comparedwith traditional histogram equalization based algorithms and it has been observed from the results that PLMHE can boost the image contrast without causing dynamic range compression,a significant change in mean brightness,and contrast-overshoot.
