Practical Backwards Compatible High Dynamic Range Compression
K. Debattista; T. Bashford Rogers; A. Chalmers University of Warwick, Coventry, United Kingdom
Abstract
High dynamic range (HDR) imaging permits the capture, storage, display, and handling of real world lighting, removing the limitations that traditional imaging has that may lead to over- and underexposed pixels in images. In order to achieve this, HDR imagery requires the storage and manipulation of floating point data, which consumes more space than the single byte per color channel employed by traditional imaging approaches. HDR video and still image compression methods do exist and have helped improve the amount of compression applied. One particular set of such methods, ...
