Simultaneous encoder for high-dynamic-range and low-dynamic-range video

IEEE Transactions on Consumer Electronics, 2016
High-dynamic-range (HDR) technology is an emerging video technology that allows displays to produce a higher range of luminance to better approximate the range of brightness perceived by the human eye. However, during the transition to this new technology, not all consumer devices will support the full range of luminance values offered by HDR. In order

Expanding low dynamic range videos for high dynamic range applications

Proceedings of the 24th Spring Conference on Computer Graphics, 2008
In this paper we introduce an algorithm and related methods that expand the contrast range of Low Dynamic Range (LDR) videos in order to regenerate missing High Dynamic Range (HDR) data. For content generated from single exposure LDR sequences, this is clearly an under constrained problem. We achieved the expansion by inverting established tone mapping

Super high dynamic range video

2016 23rd International Conference on Pattern Recognition (ICPR), 2016
High dynamic range (HDR) imaging is highly demanded in computer vision algorithms. An HDR image is composed with several low dynamic range (LDR) images, which usually have some disparities. In many HDR imaging algorithms, the disparities are estimated based on the texture information of the LDR images.

High dynamic range for contrast enhancement

IEEE Transactions on Consumer Electronics, 2006
Video image quality improving technologies produce remarkable achievements as display devices make rapid progress. However, there exist some limitations on intensity representation of display and acquisition devices to reproduce the real world video images.

High dynamic range images for enhancing low dynamic range content

SIGGRAPH Asia 2011 Posters, 2011
This poster presents a practical system for enhancing the quality of Low Dynamic Range (LDR) videos using High Dynamic Range (HDR) background images. Our technique relies on the assumption that the HDR information is static in the video footage. This assumption can be valid in many scenarios where moving subjects are the main focus of the footage and ...

Multispectral high dynamic range imaging

SPIE Proceedings, 2008
Capturing natural scenes with high dynamic range content using conventional RGB cameras generally results in saturated and underexposed and therefore compromising image areas. Furthermore the image lacks color accuracy due to a systematic color error of the RGB color filters.

High dynamic range imaging for artists

ACM SIGGRAPH 2008 classes, 2008
An introduction and overview of the practical applications and uses of high-dynamic-range imaging (HDRI) from a production point of view. The course begins with a brief overview of HDRI and pre-production, production, and post-production techniques.Topics include: RAW converters, bit depths, RAW vs JPEG, the pros and cons of various panoramic HDR ...

Super-high Dynamic Range Imaging

2014 22nd International Conference on Pattern Recognition, 2014
We propose a novel high dynamic range (HDR) imaging algorithm for the scenes that contain an extremely wide range of scene radiance. In the HDR imaging, several images are taken under different exposures. Those images usually have displacement from one another due to camera and/or object motions. The challenge of the super HDR imaging is to align those

Deep high dynamic range imaging of dynamic scenes [PDF]

ACM Transactions on Graphics, 2017
Producing a high dynamic range (HDR) image from a set of images with different exposures is a challenging process for dynamic scenes. A category of existing techniques first register the input images to a reference image and then merge the aligned images into an HDR image.

High Dynamic Range Volume Visualization

VIS 05. IEEE Visualization, 2005., 2005
High resolution volumes require high precision compositing to preserve detailed structures. This is even more desirable for volumes with high dynamic range values. After the high precision intermediate image has been computed, simply rounding up pixel values to regular display scales loses the computed details.
