摘要：

This paper presents a new approach for effectively compressing the dynamic range of a visual scene while preserving the local contrast in order to reproduce a high quality image on devices with limited dynamic range. In this method, dynamic range compression is performed through a reduction of the illumination effect, by taking into account the characteristics of the human visual system. To precisely extract the illumination component within a reasonable complexity, a multi-scale nonlinear filtering scheme, referred to here as Nonlinear Multi-scale Retinex (NMR), was developed.
