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 ...

The Layer II coder provides a higher compression rate by making some relatively minor modifications to the Layer I coding scheme. These modifications include how the samples are grouped together, the ...

Coding, information theory and compression constitute the backbone of modern digital communications and data storage. Grounded in Shannon’s seminal work, information theory quantifies the ...

Abstract: Modern medical imaging requires storage of large quantities of digitized clinical data. Due to the constrained bandwidth and storage capacity, however, a medical image must be compressed ...

Artificial intelligence (AI) can be successfully applied to images and videos to improve how they look - to add colour, to understand their content better or to help with storytelling, for instance.

Google is open-sourcing a new general purpose data compression library called Zopfli that can be used to speed up Web downloads. The Zopfli Compression Algorithm, which got its name from a Swiss bread ...

Due to the increasing consumption of more immersive video content with higher resolutions, the need for more efficient video compression techniques is starting to grow. Recently, new video compression ...

Abstract: Electroencephalography (EEG) signals generate high-dimensional data, creating challenges in storage and transmission. This paper presents an efficient EEG compression method combining ...

The video coding team within BBC R&D focuses on multiple aspects of video technology, with the general goal of supporting the delivery of high quality content to all BBC audiences. Our audiences are ...
