In MPEG Layer III coding the compression gain is mainly achieved through the unequal distribution of energy in the different frequency bands, the use of the psychoacoustic model, and Huffman coding.

A high-performance, lossless file compression tool developed in C++. This project implements the Huffman Coding algorithm from scratch to compress text files by approximately 30-40% and decompress ...

Abstract: In this paper, a new test data compression technique is proposed. The compression is achieved by reversed leading bits coding together with Huffman coding (RLBC-HC). RLBC-HC fills the ...

🛰️ What is This Project? This mini-project focuses on compressing satellite images, which are often large and data-heavy, using classic but powerful methods: DCT and Huffman Coding. DCT helps convert ...

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: Image compression is essential for storing and sending digital images efficiently. The key challenge lies in balancing compression ratio, computational cost, and image quality. This study ...
