An image with poor contrast, improper brightness, and low saturation generates a lot of missing information. This problem can be solved with enhancing the image saturation without changing the hue and range values of the image. In this paper, we compared three different hue preserving methods: Hue Preserving Image Enhancement without gamut problem, Hue and Range Preserving RGB Image Enhancement and Modified Hue Preserving Image Enhancement without gamut problem. The results were evaluated using Peak Signal Noise to Ratio as one of the references evaluation score and Blind Referenceless Image Spatial Quality Evaluator as the natural image evaluation score. From three different methods, Hue and Range Preserving RGB Image Enhancement give the best result compared the other two.
