Compression algorithms for speech, audio, still images, and video are quite complicated and, more importantly, nearly always lossy. Thus, samples often change dramatically once they’re decompressed.

At the core of CompressionX is a proprietary algorithm designed to compress data without loss. Unlike traditional utilities, ...

Abstract: The compression effect of existing lossless compression algorithm for JPEG file is poor. This paper introduces lossless compression methods combined by shuffle algorithm and lossless ...

Lossless data compression plays a vital role in addressing the growth in data volumes, real-time processing demands, and bandwidth constraints that modern systems face. Dr. Sotiropoulou will deliver ...

This project conducts an analysis of modern lossless image compression techniques, focusing on three prominent algorithms: Brotli, Deflate, and LZMA. Each algorithm is implemented to compress images ...

Common audio data formats such as the Compact Disc generally store a two-channel (stereo) audio signal. The left and fight channel data streams are stored entirely independently. Various new data ...

Over the past few years there has been a remarkable progress in the quality of display devices, with 4K displays becoming the norm, and 8K and 10K displays following closely. However, this increase in ...

This paper discusses the hardware implementation of an encoder and a decoder for the QOI lossless RGB image format. Some results are given for the AMD/Xilinx architecture, reaching over 800 Mpixels/s ...

Abstract: This paper presents a novel and generic algorithm for reduction in computational complexity associated with the estimation of LS based predictor. Many lossless compression algorithms used ...

As mentioned previously, the characteristics of typical audio signals vary from time to time and therefore we must expect the required bit rate for lossless compression to vary as well. Since the bit ...
