In this chapter we examine compression algorithms such that recovered input data cannot be exactly reconstructed from compressed version. This termed "loss". What we have, then, is a tradeoff between efficient compression versus a less accurate version of the input data. This tradeoff is captured ...
Image compression algorithms in wireless multimedia sensor networks: A survey 3 Image compression techniques Compression techniques can be classified into lossy and lossless compression techniques. If removing the redundancy is a reversible process and has no information loss, this is called lossless compre...
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...
Data compression, the process of reducing the amount of data needed for the storage or transmission of a given piece of information, typically by the use of encoding techniques. Compression predates digital technology, having been used in Morse Code, whi

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. ...

In reality, the term lossy compression is a misnomer for GIFs, whose format is palette based, because the related compression algorithms are lossless, hence no data loss in the output. Note: Because of the 8-bit GIF limit of 256 colors, converting other image formats to GIF does result ...
Our algorithm can work at any rate, unlike other lossy compression algorithms. We envisage our algorithm as being part of a more general compression scheme that works with the entire FASTQ file. Numerical experiments show that we can achieve a better mean squared error (MSE) for small rates (...
