ABSTRACT.We compare a variety of lossless image compression methods on a large sample of astronomical images and show how the compression ratios and speeds of the algorithms are affected by the amount ...

PVRIC4 enables random-access visually lossless image compression, ensuring bandwidth and memory footprint savings of at least 50%, and enabling systems to overcome performance bandwidth constraints.

The ubiquitous JPEG looks like it will be getting a major feature boost in the not too distant future. The Independent JPEG Group at the Leipzig Institute for Applied Informatics has released version ...

A display Driver with on-chip frame buffer and a scalable image compression codec reaching visually lossless image quality is presented. The frame buffer compression codec can encode and decode up to ...

This week at NAB Show in Las Vegas, the Joint Photographic Experts Group (JPEG), the international committee behind the titular image compression standard, unveiled JPEG XS, a new format that is ...

Image compression technology in the PowerVR PVRIC4 IP block enables random access, visually lossless image compression for bandwidth and memory savings for DTVs, smartphones and tablets, says ...

Brother and sister team Peter Ma and Nancy Ghaly presented Piper Pied, a lossless compression algorithm for online images, at the Disrupt NY Hackathon today. The startup is a “creative spin” on Pied ...

Image compression is an essential technique for efficient transmission and storage of images. The demands for transmission and storage of multimedia data are increasing exponentially. A gray scale ...

Imagination Technologies has unveiled the PowerVR PVRIC4, a new generation of its image compression technology which enables SoC customers targeting devices such as DTVs, smartphones and tablets to ...
