In his research, Professor Marko Huhtanen from the University of Oulu, who specializes in applied and computational ...

Image compression is an essential technique for efficient transmission and storage of images. The demands for transmission and storage of multimedia data are increasing exponentially. A gray scale ...

Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...

Founded in 2012, UK-based CompressionX has emerged from a decade of algorithmic development to launch a downloadable data compression service aimed at reshaping how businesses and individuals manage ...

There things stood until the age of the personal computer and the internet. A three-minute track on a CD (which is the length of a typical pop song) occupies 31,752,000 bytes, or just over 30MB.

People store large quantities of data in their electronic devices and transfer some of this data to others, whether for professional or personal reasons. Data compression methods are thus of the ...

Data compression works so well that popular backup and networking tools have some built in. Linux offers more than a dozen compression tools to choose from, and most of them let you pick a compression ...

Trajectory data compression and simplification techniques have emerged as essential tools for managing the ever‐increasing volumes of spatio‐temporal data generated by GPS devices and other ...
