摘要：Magnetic Resonance (MR) images provide physicians with vital information about different diseases of the human body. Thus, such images must have adequate clarity to become highly beneficial in the medical field. However, it is known that MR images have a poor dynamic range which significantly affects their visible quality due to the deficient brightness and contrast. In order to deliver evident results, a tuned single-scale Retinex algorithm is utilized in this study to ameliorate the dynamic range which eventually results in better brightness and contrast. The obtained results are compared with various algorithms that utilize contemporary, complex and renowned concepts. Moreover, many naturally-degraded MR images are used for experimental and comparable purposes. Finally, intensive experiments revealed the favorability of the adopted algorithm, in that it produced evident results without any visible flaws and outperformed the comparable algorithms in terms of visible quality.
