Abstract

Showing high dynamic range images on general displayers whose dynamic ranges are relatively low will result in images with undesirable artifacts such as underexposure or overexposure images. To display images without unwanted artifacts, a Retinex-based tone mapping method is proposed in this paper. We present the weighted edge-preserving smooth filter to estimate a smoother illumination, and a mixed tone mapping function is employed to adjust the illumination component to obtain a more pleasing image. The experimental results demonstrate that our method achieves higher contrast and richer details as compared with previous mapping methods.
