Analyzing The Losses In Visually Lossless Compression Algorithms Methods to assess algorithm quality, and observations about VESA Display Stream Compression using these algorithms.

Real-life data confirms (or contradicts) theoretically derived predictions. In a world seemingly obsessed with lossy compression, lossless codecs also have a place. CPUs’ multimedia-tuned features can ...

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 ...

Apple has open-sourced its new lossless compression algorithm, LZFSE, introduced last year with iOS 9 and OS X 10.10. According to Apple, LZFE provides the same compression gain as ZLib level 5 ...

Other uses for the algorithm could be for super simple video compression, for applications where resource is tight and some low-effort bandwidth reduction would be beneficial.

People store large quantities of data in their electronic devices and transfer some of this data to others, whether for professional or personal reasons. Data compression methods are thus of the ...

Lossless data compression plays a vital role in addressing the growth in data volumes, real-time processing demands, and bandwidth constraints that modern systems face. Dr. Sotiropoulou will deliver ...

All lossless compression algorithms for computer files exploit character redundancy and locality. LZ-based algorithms build a dictionary of frequently-used letters, words, and phrases and then replace ...

In this design, the lossless compressor handles an integer stream of baseband ADC samples. Though simple, the algorithm is effective at compressing many baseband signals without loss.

This paper proposes an innovative fusion of encryption and compression techniques that optimizes data handling and security. The approach employs a layered non-encoding encryption-compression ...
