In this paper, we propose an image processing method for color images to enhance both saturation and contrast with reversibility. Most previous work has investigated reversible contrast enhancement for grayscale images based on data hiding techniques. Meanwhile, a reversible contrast enhancement method for color images was proposed. However, this method cannot fully ensure its reversibility, and thus there exist many cases where the original image is not perfectly retrieved. In contrast, the proposed method improves not only contrast but also saturation by using HSV color space. Additionally, our method guarantees reversibility in any case. We confirm that our proposed method enhances both saturation and contrast without hue distortion and ensures full reversibility. |
