WebLe code de Huffman (1952) est un code de longueur variable optimal, c'est-à-dire tel que la longueur moyenne d'un texte codé soit minimale. On observe ainsi des réductions de taille de l'ordre de 20 à 90%. Ce code est largement utilisé, souvent combiné avec d'autres méthodes de compression.

I have some … 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. For a high sparsity Huffman tree, such as SGH-tree, Hashemian [2] proposed a condensed Huffman table …
