High Dynamic Range (HDR) Imaging using Color Gamut Mapping
2018 4th International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT), 2018Images can be mapped from Low dynamic range (LDR) to high dynamic range (HDR) using Tone Mapping to view HD images on standard display. Existing algorithm on tone mapping suffers an inherent drawback in that they often work with insufficient information and this could lead to undesirable outputs.

HDR VolVis: high dynamic range volume visualization
IEEE Transactions on Visualization and Computer Graphics, 2006In this paper, we present an interactive high dynamic range volume visualization framework (HDR VolVis) for visualizing volumetric data with both high spatial and intensity resolutions. Volumes with high dynamic range values require high precision computing during the rendering process to preserve data precision.

High dynamic range (HDR) imaging by gradient domain fusion
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011This paper proposes a new HDR imaging method in the gradient domain based on the fusion of two images with different exposure. We first formulate an energy function for the binary labeling of each pixel based on the brightness and contrast measure of each image, which gives a binary map that determines whether the under-exposed image is better than the

Color correction of high dynamic range images at HDR-level
ACM SIGGRAPH 2007 posters, 2007In recent research in representing realistic appearance of materials, HDR(High Dynamic Range) images constructed from LDR(Low Dynamic Range) images taken with different exposure time using a digital camera are used to measure radiance of materials like BRDF.

High dynamic range ("HDR") technology
ACM SIGGRAPH Computer Graphics, 2006HDR technology is the ability to display a wider range of light and dark colours on a screen. Both Valve and EA have produced videogames using HDR. Here is the scoop on what they had to say about HDR and their experiences using it.

The transition from traditional 24-bit RGB to high dynamic range (HDR) images is hindered by excessively large file formats with no backwards compatibility. In this paper, we demonstrate a simple approach to HDR encoding that parallels the evolution of color television from its grayscale beginnings.

High dynamic range (HDR) virtual bronchoscopy rendering for video tracking
SPIE Proceedings, 2007In this paper, we present the design and implementation of a new rendering method based on high dynamic range (HDR) lighting and exposure control. This rendering method is applied to create video images for a 3D virtual bronchoscopy system. One of the main optical parameters of a bronchoscope's camera is the sensor exposure.

Robust High Dynamic Range (HDR) Imaging with Complex Motion and Parallax
2021High dynamic range (HDR) imaging is widely used in consumer photography, computer game rendering, autonomous driving, and surveillance systems. Reconstructing ghosting-free HDR images of dynamic scenes from a set of multi-exposure images is a challenging task, especially with large object motion, disparity, and occlusions, leading to visible artifacts ...

Proceedings of the 13th European Conference on Visual Media Production (CVMP 2016), 2016
We introduce a novel algorithm for obtaining High Dynamic Range (HDR) videos from Standard Dynamic Range (SDR) videos with varying shutter speed or ISO per frame. This capturing technique represents today one of the most pop- ular HDR video acquisition methods, thanks to the avail- ability and the low cost of the equipment required; i.e., an off-the ...

Scrambling high dynamic range videos: Scrambling HDR videos
2016 Future Technologies Conference (FTC), 2016In this paper, a scrambling technique is integrated in a HDR (High Dynamic Range) video. Specifically, the scrambling process will be directly applied to the DCT (Discrete Cosine Transform) coefficients after quantization and before entropy coding.
