Arithmetic Coding LZ78 and LZW (GIF, Unix Compress), and LZ77 (gzip, zip lrj, zoo) ... (ACT) is an exelent collection of up-to-date comparisons of many compression algorithms with both compression ...

However, there is one major difference present but only rarely discussed: algorithmic complexity. It can correspond to the number of arithmetic operations, memory demands and bandwidth or simply the ...

This repository contains a series of exercises designed to help you learn and implement various compression algorithms from scratch using Python. The exercises gradually increase in difficulty, ...

Multimedia compression algorithms are essential for reducing the size and bandwidth of digital media files, such as audio, video, and images. They enable faster transmission, storage, and ...

In this paper, we propose a simple loss less algorithm which can compress all types of images with the same high Compression Rate. The algorithm consists of two phases. First, it removes the ...

Abstract. This paper presents a new method of lossless image compression. An image is characterized by homogeneous parts. The bit planes, which are of high weight are characterized by sequences of 0 ...

Bit Sliced Arithmetic Coding (BSAC) In addition to the Huffman coding scheme of the MPEG-2 AAC scheme, the MPEG-4 AAC scheme also provides the option of using binary arithmetic coding. The binary ...

Learn how to optimize the trade-off between compression ratio and complexity in entropy coding, a technique that reduces data size in digital communication.

About. Implementation of Huffman Coding, Arithmetic Coding and Lempel–Ziv–Welch for lossless data compression in C++, developed as part of the CSE471 Information Theory course.
