Abstract: The compression effect of existing lossless compression algorithm for JPEG file is poor. This paper introduces lossless compression methods combined by shuffle algorithm and lossless ...

A File-Compressor based on Huffman Coding, a lossless, bottom-up compression algorithm, built using C++ that can compress and decompress any text files.

This project is a command-line tool for compressing and decompressing files using the Huffman coding algorithm. It is designed for educational purposes (e.g., the Introduction to C module at HSLU) and ...

A group of MIT researchers believe they’ve found a way to speed up audio, video, and image compression by improving on the Fourier Transform. They say the new algorithm is up to ten times faster than ...

You would be forgiven for thinking that the elevator pitch for Daniel Reiter Horn’s latest project sounds familiar. That’s because there’s a good chance you saw it on HBO. In fact, everything about ...

Google just launched Zopfli, a new open source compression algorithm that can compress web content about 3 to eight 8 more densely (PDF) than the standard zlib library. Because Zopfli is compatible ...

Digitized mammograms are actually interpreted more accurately by radiologists once they have been "compressed." Though compression strips away much of the original data, it still leaves intact those ...

WEST LAFAYETTE, Ind. - When it comes to the information in a mammogram, Purdue scientists say less is more - and their findings could bring medical care to many far-flung communities. A team of ...
