Adaptive Logarithm Quantization-Based Tone Mapping for High-Dynamic Range Images

摘要

The high-dynamic range imaging technique is an attractive method using improved image capturing hardware. In this paper, a two-step adaptive logarithm quantization-based tone mapping method is proposed. First, the proposed method converts the RGB color space to the CIE XYZ color space. After that, the tone mapping from an HDR image to an LDR image is performed. In this step, the proposed method uses different tone mapping functions according to statistical characteristics of the input HDR image. Simulation results show that the proposed method outperforms other conventional approaches.
