Web1 day ago · This project is based on Huffman Coding, a lossless, bottom-up compression algorithm. It can compress and decompress any text files. To learn more about Huffman Coding and its applications in Information Theory you can refer this article. Implementation: This project supports two functions: Encode: This function Compresses any text file passed. WebHuffman code compression is used today as part of JPEG image compression, the MP3 audio compression standards, the Unix file compression command pack, and many other applications. In contrast, many audio and video file formats use a different type of compression known as lossy. With this compression type, some information is lost.

"Webcode (i.e. the Huffman tree) grows sparser and sparser from the root because of the geometrical distributions of various media sources. This sparsity either causes the problem of memory waste or enlarges the latency of locating a leaf sym-bol.
