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.

A High Throughput Encoder for High Dynamic Range Images
2007 IEEE International Conference on Image Processing, 2007An encoder for high dynamic range (HDR) images is proposed that is compatible with the JPEG2000 compression engine and can provide three different versions of the image to the user at the receiver end depending on his needs. The first version is a gray scale HDR image.

High dynamic range images for enhancing low dynamic range content
SIGGRAPH Asia 2011 Posters, 2011This 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 ...

The Naturalness of Reproduced High Dynamic Range Images
Ninth International Conference on Information Visualisation (IV'05), 2006The problem of visualizing high dynamic range images on the devices with restricted dynamic range has recently gained a lot of interest in the computer graphics community. Various so-called tone mapping operators have been proposed to face this issue. The field of tone mapping assumes thorough knowledge of both the objective and subjective attributes ...

Noise reduction in high dynamic range images
Signal, Image and Video Processing, 2011Multiple images with different exposures are used to produce a high dynamic range (HDR) image. Sometimes high-sensitivity setting is needed for capturing images in low light condition as in an indoor room. However, current digital cameras do not produce a high-quality HDR image when noise occurs in low light condition or high-sensitivity setting.

High dynamic range imaging on mobile devices
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008Natural scenes usually produce radiance maps that have a dynamic range much larger than the dynamic range of the imaging sensors. Due to this fact the captured images, almost always, contain under-exposed and saturated regions. Among several solutions, proposed in the open literature, the multi-frame approaches have been shown to produce high quality ...

Comprehensive test of high dynamic range images
2015 International Conference on Machine Learning and Cybernetics (ICMLC), 2015About few years ago, professional photographers found an easy way to achieve quality photos in a high contrast lighting condition by using High dynamic range (HDR) function. This new design enabled people to create better pictures through a mixture range of images from the same target-picture into a new digital image, instead of using Gradual Color ...
