Exploiting Light Polarization for Deep HDR Imaging from a Single Exposure
Sensors, 2023 In computational photography, high dynamic range (HDR) imaging refers to the family of techniques used to recover a wider range of intensity values compared to the limited range provided by standard sensors.

High-Dynamic-Range CT Reconstruction Based on Varying Tube-Voltage Imaging. [PDF]
PLoS ONE, 2015 For complicated structural components characterized by wide X-ray attenuation ranges, the conventional computed tomography (CT) imaging using a single tube-voltage at each rotation angle cannot obtain all structural information.

High Dynamic Range Imaging with TDC-Based CMOS SPAD Arrays
Instruments, 2019 This paper investigates the use of image sensors based on complementary metal−oxide−semiconductor (CMOS) single-photon avalanche diodes (SPADs) in high dynamic range (HDR) imaging by combining photon counts and timestamps. The proposed method

Saliency Maps of High Dynamic Range Images [PDF]
Proceedings of the 6th Symposium on Applied Perception in Graphics and Visualization, 2009 A number of computational models of visual attention have been proposed based on the concept of saliency map. Some of them have been validated as predictors of the visual scan-path of observers looking at images and videos, using oculometric data. They are widely used for Computer Graphics applications, mainly for image rendering, in order to avoid ...

High Dynamic Range Imaging by Perceptual Logarithmic Exposure Merging
International Journal of Applied Mathematics and Computer Science, 2015 In this paper we emphasize a similarity between the logarithmic type image processing (LTIP) model and the Naka–Rushton model of the human visual system (HVS).

Sparse signal recovery from modulo observations
EURASIP Journal on Advances in Signal Processing, 2021 We consider the problem of reconstructing a signal from under-determined modulo observations (or measurements). This observation model is inspired by a relatively new imaging mechanism called modulo imaging, which can be used to extend the dynamic range ...

High-capacity watermarking of high dynamic range images [PDF]
EURASIP Journal on Image and Video Processing, 2016 High dynamic range (HDR) imaging techniques address the need to capture the full range of color and light that the human eyes can perceive in the real world. HDR technology is becoming more and more pervasive. In fact, most of the cameras and smartphones available on the market are capable of capturing HDR images.

High Dynamic Range and Super-Resolution Imaging From a Single Image
IEEE Access, 2018 This paper presents an algorithm for high dynamic range (HDR) and super-resolution (SR) imaging from a single image. First, we propose a new single image HDR imaging (HDRI) method based on the Retinex approach and exploit a recent single image SR method ...

Glare encoding of high dynamic range images [PDF]
CVPR 2011, 2011 Without specialized sensor technology or custom, multi-chip cameras, high dynamic range imaging typically involves time-sequential capture of multiple photographs. The obvious downside to this approach is that it cannot easily be applied to images with moving objects, especially if the motions are complex.
