WebFeb 18, 2024 · 1.1 Huffman Coding. Huffman coding is an effective lossless data compression method. It belongs to the class of statistical-based compression technique. It is a variable length encoding scheme that involves assignment of fewer bits to symbols that occur more frequently and more bits to symbols that appear less often. The worst case for Huffman coding can happen when the probability of the most likely symbol far exceeds 2 −1 = 0.5, making the upper limit of inefficiency unbounded. There are two related approaches for getting around this particular inefficiency while still using Huffman coding.
