Inverse Tone Mapping Based upon Retina Response

The Scientific World Journal, 2014
The development of high dynamic range (HDR) display arouses the research of inverse tone mapping methods, which expand dynamic range of the low dynamic range (LDR) image to match that of HDR monitor.

Learning Preferential Perceptual Exposure for HDR Displays

IEEE Access, 2019
High dynamic range (HDR) displays are capable of displaying a wider dynamic range of values than conventional displays. As HDR content becomes more ubiquitous, the use of these displays is likely to accelerate.

Afatinib Overcomes Osimertinib Resistance via Egfr V804F Mutation in a Syngeneic Egfr‐Mutant Lung Cancer Mouse Model

Cancer Science, EarlyView.
Using an immunocompetent mouse model of Egfr Ex19del‐driven lung cancer, we found that osimertinib‐resistant tumors acquired Egfr V804F, the murine counterpart of human EGFR V802F. Afatinib, but not osimertinib, suppressed phosphorylation of EGFR and overcame V804F‐mediated resistance, providing a preclinical rationale for biomarker‐guided therapy ...

Bracket Diffusion: HDR Image Generation by Consistent LDR Denoising

We demonstrate generating HDR images using the concerted action of multiple black-box, pre-trained LDR image diffusion models. Common diffusion models are not HDR as, first, there is no sufficiently large HDR image dataset available to re-train them, and,

Multiexposed Image-Fusion Strategy Using Mutual Image Translation Learning with Multiscale Surround Switching Maps

Mathematics
The dynamic range of an image represents the difference between its darkest and brightest areas, a crucial concept in digital image processing and computer vision.

A case of a superficial spreading melanoma in situ diagnosed via digital dermoscopic monitoring with high dynamic range conversion

Dermatology Practical & Conceptual, 2019
A 48-year-old woman presented with a 3 mm, pigmented macule at her first visit to our clinic. The macule, which showed complete symmetry and a typical network, was tentatively diagnosed as a Clark nevus; a 6-month follow-up was recommended, and the ...

PSHead: 3D Head Reconstruction from a Single Image with Diffusion Prior and Self‐Enhancement

Computer Graphics Forum, EarlyView.
We introduce PSHead, a coarse‐to‐fine framework guided by both object and face priors, to produce a Gaussian‐based 3D avatar for a single frontal‐view reference image. In the coarse stage, we create an initial 3D representation by applying diffusion models trained for general object generation, using Score Distillation Sampling losses over novel views.

Tone mapping based on fast image decomposition and multi‐layer fusion

IET Computer Vision, 2015
To solve the problem of low efficiency and colour distortion in several typical tone mapping operators for high dynamic range (HDR) images, the authors propose a novel tone mapping algorithm based on fast image decomposition and multi‐layer fusion.

Democratising Multi‐Projector Displays

Computer Graphics Forum, EarlyView.
Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...
