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 ...

Coding, information theory and compression provide a unified framework for quantifying, transmitting and summarising data. At its heart lies the concept of entropy, which measures the average ...

Implementation of Huffman coding for both compression and decompression of binary files. It begins by reading an input binary file, 'balloon.jpg', and compressing its contents using Huffman coding, ...

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 ...

Abstract: Traditional video compression coding methods, such as H.26x series and MPEG series standards, have some problems such as low coding efficiency and poor adaptability, and it is difficult to ...

Abstract: With growing demand for point cloud coding, Video-based Point Cloud Compression (V-PCC) is released for dynamic point clouds, relying on mature 2D video coding techniques. However, the huge ...

We are currently researching a video and audio coding technologies for advanced terrestrial broadcasting. Here, we present a real-time versatile video coding (VVC *) decoder that supports multilayer ...

This repository provides code for studying hybrid text compression pipelines that combine transformer-based Large Language Models (LLMs) with Arithmetic Coding (AC). In this framework, an LLM is used ...

An ordinance from the Ministry of Internal Affairs and Communications (MIC) was issued in 2011 on revision of the audio coding formats of 8K Super Hi-Vision (8K) broadcasting using 22.2 multichannel ...
