Abstract

The dynamic range of many real-world environments exceeds the capabilities of current display technology by several orders of magnitude. To obtain reasonable reproduction, a large number of high-quality tone-mapping operators are currently available. All of these methods can be divided into three kinds: global operation, local operation and temporal-related algorithm. As an effective local operation to avoid halo artifacts, bi-lateral filter is presented and discussed in recent years. After analysis in-depth, this paper presents an improved bi-lateral filter in high dynamic range compression focused on four points: calculating efficiency, vision theory support, scales and parameters. Experiments indicate that the new operator can generate reasonable reproduction of high dynamic range images.
