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 ...

Algorithms for compression of high dynamic range images and video

Lossy 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 As display technology makes progress, these formats no longer represent the data that new devices can display.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...

Extending 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...
