The State of the Art in HDR Deghosting: A Survey and Evaluation
TL;DR: A taxonomy of deghosting algorithms is proposed which can be used to group existing and future algorithms into meaningful classes, and the results of a subjective experiment are shared which aims to evaluate various state‐of‐the‐art de ghosting algorithms.
Journal ArticleDOI
Noise reduction in high dynamic range imaging
Ahmet Oğuz Akyüz,Erik Reinhard +1 more
TL;DR: This work presents a robust and efficient technique to significantly reduce noise in an HDR image even when its constituent exposures are taken at very high ISO settings.
Journal ArticleDOI
Color appearance in high-dynamic-range imaging
Ahmet Oğuz Akyüz,Erik Reinhard +1 more
TL;DR: This work proposes to augment current tone reproduction operators with the application of color appearance models as an independent preprocessing step to preserve chromatic appearance across scene and display environments to prepare an image for display.
Journal ArticleDOI
An Objective Deghosting Quality Metric for HDR Images
TL;DR: An objective metric is proposed which aims to simplify the process of reconstructing high dynamic range images of a complex scene involving moving objects and dynamic backgrounds by taking a stack of input exposures and the deghosting result and producing a set of artifact maps for different types of artifacts.
Journal ArticleDOI
A Reliable and Reversible Image Privacy Protection Based on False Colors
TL;DR: Two fully reversible privacy protection schemes implemented within the JPEG architecture are proposed by using false colors with the first scheme being adaptable to other privacy protection filters while the second is false color-specific.
