Puma: A High-Quality Retinex-Based Tone Mapping Operator
Tone mapping is the process of compressing high dynamic range (HDR) images to obtain low dynamic range (LDR) images in order to display them on standard display devices. The methods that perform tone mapping also known as tone mapping operators (TMOs) can be global and process all luminances in the same way, or they can be local and process the luminances with respect to their closer neighborhood. While the former tend to be faster, the latter are known to produce results of significantly higher quality. In this paper perceptually-based tone mapping is combined with one of the latest Retinex-based methods to create a high-quality TMO. The new TMO requires only a constant number of steps per pixel and experimental results show that it outperforms all but one state-of-the-art TMOs in terms of tone mapped LDR image quality. The source code is available at http://www.fer.unizg.hr/ipg/resources/color_constancy/.
