WebAug 26, 2016 · Huffman coding [11] is a most popular technique for generating prefix-free codes [7, 10]. It is an efficient algorithm in the field of source coding. It produces the lowest possible number of code symbols of a single source symbol [1]. Huffman coding is a most widely used lossless compression technique [2]. However, there are some limitations … WebSep 4, 2024 · Huffman coding from scratch with Elixir. Huffman coding is a pretty straight-forward lossless compression algorithm first described in 1992 by David Huffman. It utilizes a binary tree as its base and it's quite an easy to grasp algorithm. In this post we walk through implementing a Huffman coder and decoder from scratch using Elixir ⚗️.
