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 ...

We build a state model of the DC coefficients of the entire image. On each 8x8 block in the image, we perform DCT, quantization, and run length encoding on the resulting coefficients. Normally ...

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 ...

Abstract: Image compression is the application of data compression technology in digital images, aiming at reducing redundant information in image data and storing and transmitting data in a more ...

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 ...

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 ...

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 ...

Abstract: With the rapid growth of multimedia technology, sharing of multimedia components have become a common practice. Thus, compression of image has become an integral approach that motivates the ...
