Text Compression using Canonical Huffman Coding

Webcalled Huffman coding. The characters in a data file are converted to a binary code, where the common characters in the file have shortest binary codes. To observe Huffman coding function, a text file should be compressed, and the characters in the file have following frequencies: Table 1. Huffman Coding Table Symbols frequencies A 8 B 10 E 32 WebApplication Example 3.5 Huffman Coding for Text Compression. Text compression algorithms aim at statistical reductions in the volume of data. One commonly used compression algorithm is Huffman coding [Huf52], which makes use of information on the frequency of characters to assign variable-length codes to characters.
