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 ...
Lossy compression is also suitable for websites featuring JPEG files and fast loading times since the compression ratio can be adjusted while maintaining the right balance. Algorithms used in lossless and lossy compression Different kinds of algorithms are used to reduce file sizes in lossless and lo...
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
making the development of efficient compression algorithms increasingly important. Traditional codecs, which use handcrafted transformations [1,42], are now outperformed by data-driven neural image compression (NIC) [7,8,33] methods that optimize for both rate and distortion. Nevertheless, most curren...
Lossy algorithms. Lossy compressionis typically used when a file can afford to lose some data, and/or if storage space needs to be drastically ‘freed up’. Here, an algorithm scans image files and reduces their size by discarding information considered less important or undetectable to the huma...

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. ...
This paper focuses on developing effective and efficient algorithms for compressing scientific simulation data computed on structured and unstructured grids. A paradigm for lossy compression of this data is proposed in which the data computed on the grid
