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 ...

High dynamic range panoramic imaging

Proceedings Eighth IEEE International Conference on Computer Vision. ICCV 2001, 2002
Most imaging sensors have a limited dynamic range and hence can satisfactorily respond to only a part of illumination levels present in a scene. This is particularly disadvantageous for omnidirectional and panoramic cameras since larger fields of view have larger brightness ranges.

Penrose high-dynamic-range imaging

Journal of Electronic Imaging, 2016
High-dynamic-range (HDR) imaging is becoming increasingly popular and widespread. The most common multishot HDR approach, based on multiple low-dynamic-range images captured with different expo- sures, has difficulties in handling camera and object movements.

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

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.

High Dynamic Range Global Mosaic

2006
This paper presents a global approach for constructing high dynamic range mosaic from multiple images with large exposure differences. By relating image intensities to scene radiances with a convenient distortion model, we robustly estimated registration parameters for the high dynamic range global mosaic (HDRGM), simultaneously estimating scene ...

Advanced High Dynamic Range Imaging

2011
This book explores the methods needed for creating and manipulating HDR content. HDR is a step change from traditional imaging; more closely matching what we see with our eyes. In the years since the first edition of this book appeared, HDR has become much more widespread, moving from a research concept to a standard imaging method.

High Dynamic Range Display Systems

ACM Transactions on Graphics, 2004
The dynamic range of many real-world environments exceeds the capabilities of current display technology by several orders of magnitude. In this paper we discuss the design of two different display systems that are capable of displaying images with a dynamic range much more similar to that encountered in the real world.

High Dynamic Range Display Adopting High Dynamic Range Imaging Technique

2006 IEEE LEOS Annual Meeting Conference Proceedings, 2006
Technique of high dynamic range imaging (HDRI) was introduced into conventional high dynamic range display (HDRD). Sharpness of image was further enhanced by improving local contrast ratio in the HDRI-based high dynamic range display.
