Effective Compression of High Dynamic Range Images
There's a plenty of file formats designed for storing high dynamic range (HDR) images. But none of them provide satisfactory compression ratio and backward compatibility with existing file formats. In this paper we propose an approach to lossy compressing HDR data in a standard JPEG/JFIF file. An original HDR file is decomposed into a tone mapped version of it LDR (low dynamic range) 24bpp and ...
متن کاملHigh-dynamic-range scene compression in humans
Single pixel dynamic-range compression alters a particular input value to a unique output value a look-up table. It is used in chemical and most digital photographic systems having S-shaped transforms to render high-range scenes onto low-range media. Postreceptor neural processing is spatial, as shown by the physiological experiments of Dowling, Barlow, Kuffler, and Hubel & Wiesel. Human vision...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
متن کاملLossy compression of high dynamic range images and video
Most common image and video formats have been designed to work with existing output devices, like LCD or CRT monitors. As display technology makes progress, these formats no longer represent the data that new devices can display. Therefore a shift towards higher precision image and video formats is imminent. To overcome limitations of common image and video formats, such as JPEG, PNG or MPEG, w...
متن کاملImpact of Tone Mapping in High Dynamic Range Image Compression
Tone mapping or range reduction is often used in High Dynamic Range (HDR) visual signal compression to take advantage of the existing image/video coding architectures. Thus, it is important to study the impact of tone mapping on the visual quality of decompressed HDR visual signals. To our knowledge, most of the existing studies focus only on the quality loss in the resultant low dynamic range ...
