High Dynamic Range Imaging: Providing a Step Change in Imaging Technology

Most high dynamic range image HDRI algorithms assume stationary scene for registering multiple images which are taken under different exposure settings. In practice, however, there can be some global or local movements between images caused by either camera or object motions. This situation usually causes ghost artifacts which make the same object appear multiple times in the resultant HDRI. To solve this problem, most conventional algorithms conduct ghost detection procedures followed by ghost region filling with the estimated radiance values. However, usually these methods largely depend on the accuracy of the ghost detection results, and thus often suffer from color artifacts around the ghost regions.

High Dynamic Range Imaging, Second Edition , is an essential resource for anyone working with images, whether it is for computer graphics, film, video, photography, or lighting design. It describes HDRI technology in its entirety and covers a wide-range of topics, from capture devices to tone reproduction and image-based lighting. The techniques described enable students to produce images that have a dynamic range much closer to that found in the real world, leading to an unparalleled visual experience. All existing chapters have been updated to reflect the current state-of-the-art technology. As both an introduction to the field and an authoritative technical reference, this book is essential for anyone working with images, whether in computer graphics, film, video, photography, or lighting design. Engineering staff i. He is interested in the interface between visual perception and computer graphics and also in high dynamic range image editing.

The luminous value is high for many natural scenes, which causes loss of information and occurs in dark images. The High Dynamic Range HDR technique captures the same objects or scene for multiple times in different exposure and produces the images with proper illumination. This technique is used in the various applications such as medical imaging and observing the skylight, etc.

Image Forensics of High Dynamic Range Imaging

High-dynamic-range rendering HDRR or HDR rendering , also known as high-dynamic-range lighting , is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range HDR. This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer-generated movies and special effects benefit from this as it creates more realistic scenes than with the more simplistic lighting models used. Graphics processor company Nvidia summarizes the motivation for HDR in three points: bright things can be really bright, dark things can be really dark, and details can be seen in both. The use of high-dynamic-range imaging HDRI in computer graphics was introduced by Greg Ward in with his open-source Radiance rendering and lighting simulation software which created the first file format to retain a high-dynamic-range image.

By faithfully representing the wide range of colours and intensities that our eyes can see, HDR is in real world-units rather than device-units, encompassing all future imaging systems intended for the human eye. The potential impact that HDR technology is large as it embraces all aspects of digital imaging, ranging from scientific image processing and high fidelity production of photo realistic computer graphics to home-entertainment. Within the given scenario, this special issue is timely and aimed at raising the level of awareness of the signal processing community with respect to the challenges to be tackled when dealing with HDR acquisition, processing, and delivery of different kind of media including images, video and multi view video. The special issue will be a stimulating window on the very latest research and challenges within this rapidly emerging field. High dynamic range HDR imaging techniques address the need to capture the full range of color and light that the human eyes can perceive in the real world. HDR technology is becoming more and more pervasive Authors: Emanuele Maiorana and Patrizio Campisi.

In a hands-on approach, we show how HDR images and video can be captured, the file formats available to store them, and the algorithms required to prepare them for display on low dynamic range displays. The trade-offs at each step are assessed allowing attendees to make informed choices about data capture techniques, file formats and tone reproduction operators. In addition, the latest developments in image-based lighting will be presented. Prerequisites None.
