High dynamic range panoramic imaging
Proceedings Eighth IEEE International Conference on Computer Vision. ICCV 2001, 2002Most 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, 2016High-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.

High dynamic range imaging with PERIODIC
Proceedings of the 46th Annual Southeast Regional Conference on XX, 2008This paper presents an approach for improving the effective dynamic range of a novel array imaging systems by using multiple images of the same scene taken with different exposure times and gain values. In this approach, multiple images are fused into a single high dynamic range radiance map whose intensities are proportional to the true radiance ...

High Dynamic Range Global Mosaic
2006This 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 ...

High Dynamic Range Display Systems
ACM Transactions on Graphics, 2004The 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, 2006Technique 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.

High dynamic range ultrasound imaging
International Journal of Computer Assisted Radiology and Surgery, 2018High dynamic range (HDR) imaging is a popular computational photography technique that has found its way into every modern smartphone and camera. In HDR imaging, images acquired at different exposures are combined to increase the luminance range of the final image, thereby extending the limited dynamic range of the camera.

High-dynamic-range video solution
ACM SIGGRAPH ASIA 2009 Art Gallery & Emerging Technologies: Adaptation, 2009The natural world presents our visual system with a wide, ever-changing range of colors and intensities. Existing video cameras are only capable of capturing a limited part of this wide range with sufficient resolution. High-dynamic-range (HDR) images can represent most of the real world's luminances, but until now capturing HDR images with a linear ...

Approaches to high dynamic range video
2016 Digital Media Industry & Academic Forum (DMIAF), 2016The television industry is excited about high dynamic range (HDR) video and its potential for dramatic improvements in picture quality. Together with wide colour gamut, brighter displays and ultra-high definition resolution, HDR represents a fundamental change in television which is, arguably, the biggest change since the development of colour ...

Noise in high dynamic range imaging
2008 15th IEEE International Conference on Image Processing, 2008High dynamic range (HDR) imaging is more and more widely used to increase the limited dynamic range of digital cameras and, in turn, to cover the dynamic range of the acquired scene. This image acquisition process can be subdivided into two steps. The first step is the measurement or estimation of the mostly non-linear camera transfer function (CTF ...
