Huffman coding is a lossless data compression algorithm, designed by David A. Huffman while he was a PhD student at MIT in 1952. It’s a method of variable-length encoding used to compress data by ...

ABSTRACT: Data compression plays a key role in optimizing the use of memory storage space and also reducing latency in data transmission. In this paper, we are interested in lossless compression ...

With the rapid development of multimedia technology and the massive accumulation of user data, a huge amount of data is rapidly generated and shared over the network, while the problems of ...

Zainab Falak is a seasoned technical writer, who has been creating troubleshooting guides and how-to articles for Microsoft Windows since 2019. Her expertise lies in creating concise and effective ...

File compression is the process of reducing the size of a file while preserving its content. This is typically used to save storage space, reduce transfer time over the internet, and enhance system ...

One student’s desire to get out of a final exam led to the ubiquitous algorithm that shrinks data without sacrificing information. With more than 9 billion gigabytes of information traveling the ...

Abstract: Image privacy protection and management face many challenges, such as privacy disclosure, copyright dispute, and traceability difficulties, with the development of big data. Reversible data ...

We consider the attributes of a point cloud as samples of a vector-valued volumetric function at discrete positions. To compress the attributes given the positions, we compress the parameters of the ...

Resources are always limited. Whether storage space or communication bandwidth, is not usually sufficient, which inspires us to apply compression that aims to reduce the number of bits needed to ...

We propose the first practical learned lossless image compression system, L3C, and show that it outperforms the popular engineered codecs, PNG, WebP and JPEG 2000. At the core of our method is a fully ...
