High Dynamic Range Imaging [PDF]
, 2006 High dynamic range imaging produces images with a much greater range of light and color than conventional imaging. The effect is stunning, as great as the difference between black-and-white and color television.

Super-high Dynamic Range Imaging
2014 22nd International Conference on Pattern Recognition, 2014We 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 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 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.

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 ...

Advanced High Dynamic Range Imaging
2011This 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.

Split Aperture Imaging for High Dynamic Range
International Journal of Computer Vision, 2002Most imaging sensors have limited dynamic range and hence are sensitive to only a part of the illumination range present in a natural scene. The dynamic range can be improved by acquiring multiple images of the same scene under different exposure settings and then combining them.

2013 International Conference on Communication Systems and Network Technologies, 2013
While real scenes produce a wide range of brightness variations, current cameras use low dynamic range image detector that typically provide 256 levels of brightness data at each pixel. We propose methods to create High Dynamic Range images, the method to enhance the dynamic range of is based on capturing multiple exposure photographs of the scene ...

High-Dynamic-Range Image Reproduction Methods
IEEE Transactions on Instrumentation and Measurement, 2006The high dynamic range of illumination may cause serious distortions and problems in the viewing and further processing of digital images. Important information can be hidden in the highly or extremely lowly illuminated parts. This paper deals with the reproduction of such images and introduces two new tone reproduction preprocessing algorithms which ...

Streamed high dynamic range imaging
2012 International Conference on Field-Programmable Technology, 2012The problem of mapping from a high dynamic range image, or a series of images spanning a wide dynamic range, to a standard 8-bit image is considered. Several techniques for dynamic range compression are reviewed. FPGA implementations are developed and demonstrated, with a focus on directly processing the video stream from the camera.
