Abstract

For the detection of tumors, vascular lesion and numerous other diseases, computed tomography(CT) and magnetic resource imaging (MRI) are considered as two vital medical imaging modal. However, various noises such as speckle noise, salt-pepper noise, etc. corrupt the imaging which makes the analysis of clinical data difficult. Therefore, to get a sharp and clear image for diagnostic purposes, medical image enhancement is must which removes noises and enhance the contrast of the image which helps in accurate diagnosis. In this work, brain MRI images are being enhanced through grey wolf optimization based logarithmic transformation. Logarithmic transformation increases the dynamic range value of the pixels with low intensity. GWO is a meta-heuristic approach that is used to maximize the fitness of the results. The outcome of the recommended methodology have been compared with the results of GA, PSO and CS optimizer. To measure the robustness of the technique various Image Quality Analysis(IQA) such as mean square error, peak signal to noise ratio(PSNR) as well as execution time has been compared.
