Color and Imaging Conference, 2003
Color imaging systems are continuously improving, and have now improved to the point of capturing high dynamic range scenes. Unfortunately most commercially available color display devices, such as CRTs and LCDs, are limited in their dynamic range. It is necessary to tone-map, or render, the high dynamic range images in order to display them onto a ...

Generating stereoscopic HDR images using HDR-LDR image pairs
ACM Transactions on Applied Perception, 2013A number of novel imaging technologies have been gaining popularity over the past few years. Foremost among these are stereoscopy and high dynamic range (HDR) Imaging. While a large body of research has looked into each of these imaging technologies independently, very little work has attempted to combine them.

Radiometric calibration for HDR imaging
2015 IEEE International Conference on Image Processing (ICIP), 2015In this paper we present a method to estimate the radiance map and camera response function for high dynamic range (HDR) imaging which is devoid of free parameters and can reliably recover HDR images with as few as two low-dynamic range (LDR) views acquired at different exposures.

An Application of HDR in Medical Imaging
2016We describe a solution aimed at overcoming dynamic range problems in the visualization of medical images. We first analyze the specific requirements for a high dynamic range (HDR) display that should operate in the medical (diagnostic) context, and the procedures that are followed in a laboratory of the US Food and Drug Administration to evaluate such ...

HDR Image Compression with Convolutional Autoencoder
2020 IEEE International Conference on Visual Communications and Image Processing (VCIP), 2020As one of the next-generation multimedia technology, high dynamic range (HDR) imaging technology has been widely applied. Due to its wider color range, HDR image brings greater compression and storage burden compared with traditional LDR image. To solve this problem, in this paper, a two-layer HDR image compression framework based on convolutional ...

SIGGRAPH Asia 2018 Posters, 2018
The dynamic range of display is much lower than the one perceived by human eye. This problem has been studied in both aspects of photography and display [Debevec and Malik 1997; Hirsch et al. 2014].

2018 26th Telecommunications Forum (TELFOR), 2018
Improving image quality by expanding the dynamic range has been intensively used recently. This results in the presence of much more details in the image, which is very important in most applications. The spread of the dynamic range has its limits and they are defined by the physical limits of the sensor used, i.e. the limitations of its A/D converter.

Testing HDR Image Rendering Algorithms
Color and Imaging Conference, 2004Eight high-dynamic-range image rendering algorithms were tested using ten high-dynamic-range pictorial images. A large-scale paired comparison psychophysical experiment was developed containing two sections, comparing the overall rendering performances and grayscale tone mapping performance respectively.

Fast bilateral filter for HDR imaging
Journal of Visual Communication and Image Representation, 2012Bilateral filtering is a method often used in image processing applications. It is specifically useful for HDR algorithms. A novel approach to a fast and close approximation of bilateral filtering is presented. The method is designed especially with a focus on HDR image conversion into a normal color space processing.

Image and video compression for HDR content
SPIE Proceedings, 2012High Dynamic Range (HDR) technology can offer high levels of immersion with a dynamic range meeting and exceeding that of the Human Visual System (HVS). A primary drawback with HDR images and video is that memory and bandwidth requirements are significantly higher than for conventional images and video.
