Jul 10, 2024 · Examples of Data Compression. Text compression: Where text files are compressed using algorithms, such as Huffman coding so that the size decreases. Image Compression: The JPEG format compresses images by reducing resolution and color depth. Audio Compression: MP3 format compresses audio by eliminating inaudible frequencies.

Mar 18, 2018 · This paper proposes a cluster of novel and hybrid efficient text and image compression algorithms employing efficient data structures like Hash and Graphs. We have retrieved optimal set of patterns through pruning which is efficient in terms of database scan/storage space by reducing the code table size.

Aug 26, 2024 · Compression algorithms are classified into two broad categories: lossless and lossy. Lossless compression ensures that the original data can be perfectly reconstructed from the compressed...

Feb 1, 2021 · As lossless compression, lossy compression, text compression, image compression, audio compression, video compression, bit reduction and data redundancy terms are the fundamental concepts involved in DC, a search was made using these keywords.

Data Compression algorithms present a space-time complexity trade-off between the bytes needed to store or transmit information, and the Computational resources needed to perform the encoding and decoding.

May 10, 2024 · Hence, for text file compression in this article, we decide to leverage an algorithm that gives lossless compression and uses variable-length encoding with prefix rule. The article also focuses on regenerating the original file using the decoding process.

Jun 7, 2018 · seminal algorithms of Text/Image compression are developed using various Frequent Pattern Mining(FPM)/Clustering techniques. This paper proposes a cluster of novel and hybrid efficient text and image compression algorithms employing efficient data structures like Hash and Graphs.

Apr 23, 2019 · ・Parkinson’s law: data expands to fill space available. ・Text, images, sound, video, ... Basic concepts ancient (1950s), best technology recently developed. 90% of the data in the world today has been created in the last two years alone. Generic file compression. ・Files: Gzip, bzip2, 7z. ・Archivers: PKZIP.

Understand Compression Algorithms, its Types, List, and Working. Learn how this reduce data size, their applications, and how they function effectively.

Nov 2, 2021 · A novel data compression perspective of data mining is explored in this research and the paper focuses on novel frequent sequence/pattern mining approach to text compression. This work attempts to make use of longer-range correlations between words in languages for achieving better text compression.
