WebFig.4.2 shows Huffman having the higher compression ratio, the implication is that it compresses more than Delta algorithm. ... The advantage of Huffman coding is in the average number of bits per ... WebHuffman coding is an efficient method of data compression, as it assigns shorter codes to symbols that appear more frequently in the dataset. This results in a higher compression ratio. Huffman coding is a prefix coding scheme, which means that it does not require any special markers to separate different codes.
