Lightness Perception in Tone Reproduction for High Dynamic Range Images
An anchoring theory of lightness perception comprehensively explains many characteristics of human visual system such as lightness constancy and its spectacular failures which are important in the perception of images. We present a novel approach to tone mapping of high dynamic range (HDR) images which is inspired by the anchoring theory. The key concept of this method is the decomposition of a...
متن کاملZonal brightness coherency for video tone mapping
Tone Mapping Operators (TMOs) compress High Dynamic Range (HDR) contents to address Low Dynamic Range (LDR) displays. While many solutions have been designed over the last decade, only few of them can cope with video sequences. Indeed, these TMOs tone map each frame of a video sequence separately, which results in temporal incoherency. Two main types of temporal incoherency are usually consider...
متن کاملEvaluation of HDR Tone Mapping Algorithms using a High-Dynamic-Range Display to Emulate Real Scenes
Jiangtao Kuang Rodney Heckaman Mark D. Fairchild (SID Member) Abstract — Current HDR display technology approaches the dynamic-range capabilities of the fully adapted human visual system. As such, this technology has potential for performing as a surrogate for real-world scenes in the perceptual evaluation of high-dynamic-range (HDR) image-reproduction algorithms that aim to map HDR scenes to t...
متن کاملTone Mapping for High Dynamic Range Cameras
High dynamic range images must be tone mapped before being displayed on devices with low output dynamic range. Two existing global tone mapping operators are evaluated and then a new improved operator using a sigmoid compression curve is proposed. It is then demonstrated through simulation and experimental results that an existing capture device, used previously only for simple logarithmic comp...
متن کاملTemporal Coherency in Video Tone Mapping, A Survey
High Dynamic Range (HDR) video acquisition and display is now achievable thanks to recent advances in the HDR field. Tone Mapping Operators (TMOs) convert HDR images to Low Dynamic Range (LDR) ones. However, these operators do not take into account the temporal correlation present in a video sequence. We first present in this article, two main issues that arise when dealing with video tone mapp...
