This study compares the compression results obtained with 672 algorithms, mostly based on the Huffman coding approach which constitute the state-of-the-art for scientific data manipulation, including Computational Fluid Dynamics (CFD). We also have incorporated data preprocessing...
comparison efficiencylossless image compressionpalmprint imageIn this study, lossless grayscale image compression methods are compared on public palmprint image databases. Effect of lossy compression algorithms on biometric samples has been well studied. However, lossless compression algorithms on the ...
Lossless algorithms. Withlossless compressionthe file data is restored and rebuilt in its original form after decompression, enabling the image to take up less space without any discernible loss in picture quality. No data is lost and as the process can be reversed, it’s also known as reversib...

The result: forget traditional zip, it's not compressing WAVs that well (that said, newer zip formats allow modular compression algorithms, which might be similar in result to 7z or rar). RAR's compression is best, right after FLAC, and 7z in default performs nicely as well. ...
A novel predictive-based, lossless image compression algorithm with a simple context-based entropy coder is presented, as well. A comparison with standardized lossless compression algorithms JPEG-LS and JPEG2000 is made on a large set of 12-bit medical images of different modalities and 12-bit ...
We used the identical range coding for the residual encoding of all DPCM-based algorithms. To save space, Method 1 and 2 in the tables indicate classical and online DPCM using the least squares method, respectively. 3.2. Comparison of compression performance Fig. 9 shows a comparison of ...

Compressed audio formats use compression algorithms toreduce the sizeof an audio file without sacrificing too much audio quality. They’re a great solution to save disk space, and a smaller file size doesn’t necessarily mean a huge quality loss, at least for the occasional listener. ...
Better compression ratio than most lossless compression algorithms (JPEG2000, PNG, etc.) Near-Lossless Compression Enables greater compression with visually lossless quality by constraining the maximum difference between reconstructed and original image samples Maximum image resolution of 64Kx64K, or highe...
