Objective Quality Assessment of Tone-Mapped Images
2013
IEEE Transactions on Image Processing
Preserved Fulltext
Validations using independent subject-rated image databases show good correlations between subjective ranking score and the proposed tone-mapped image quality index (TMQI). ...
Furthermore, we demonstrate the extended applications of TMQI using two examples-parameter tuning for TMOs and adaptive fusion of multiple tone-mapped images. 1 Index Terms-High dynamic range image, image ...
Moreover, we demonstrate that TMQI can be employed for optimizing parameters in TMOs and for adaptively fusing multiple tone mapped images.

We optimize the tone mapping network by minimizing the normalized Laplacian pyramid distance (NLPD), a perceptual metric calibrated against human judgments of tone-mapped image quality. ...
By doing so, the proposed TMO is fully automatic to tone map uncalibrated HDR images. ...
More generally, HDR image tone mapping can be formulated as a constrained optimization problem [25] , [26] : I = arg min I (S, I), s.t. ...

In this paper, we address this problem by proposing a fast, parameter-free and scene-adaptable deep tone mapping operator (DeepTMO) that yields a high-resolution and high-subjective quality tone mapped ...
A computationally fast tone mapping operator (TMO) that can quickly adapt to a wide spectrum of high dynamic range (HDR) content is quintessential for visualization on varied low dynamic range (LDR) output ...
