    FLAC Decoder/Encoder

    FLAC Decoder/Encoder

    Hardware FLAC Encoder / Decoder

    FLAC (Free Lossless Audio Codec) is a Codec for Lossless Compression of digital audio. Digital audio compressed by FLAC's algorithm can typically be reduced to 50–60% of its original size and decompressed to an identical copy of the original audio data. FLAC is an open format with royalty-free licensing and a reference implementation which is free software. This project is High Performance, Low Power and High Quality FLAC Encoder and Decoder on HDL Code for FPGAs or ASICs synthesis.

    DNAcompact

    Genome compression algorithm with/without reference (Linux/Windows)

    As the technique of acquiring genome sequences advances, the storage and data transferring of large genome data are becoming important concerns for biomedical researchers. We propose a two pass genome compression algorithm, which highlights the synthesis of complementary contextual models and the introduction of logistic regression mixture method, to improve the compression performance. The proposed framework handles genome compression with and without reference seque- nces, and demonstrated...

    Parallel DPCM

    C# Parallel implementation of DPCM alogrithm

    An implementation of the DPCM algorithm for compressing and decompressing an avi video file. It shows the compression size, as it is saved in a txt file near the avi original file. The decompression results in another avi file, saved near the original file. If the width and height of the frames aren't a multiple of 16, they are completed with black pixels. The pixel macroblocks of 16x16 are generated on separate threads for each frame and they are replaced on frames at decompression...
