Webba) Find the efficiency of binary Huffman code used to encode each level pixel. b) Find the average amount of coded information per image. c) Compare your result if a fixed-length code is used instead. 6. Show that a 100% coding efficiency is always obtained when using: 1- Binary Shannon code 2- Binary Fano code 3- Binary Huffman code Webb14 juli 2006 · Abstract: We consider using Shannon-Fano-Elias codes for data encryption. In many applications both compression and security are required. If the cryptanalyst knows the code construction rule and the probability mass function of the source, then Huffman code provides no ambiguity, but Shannon-Fano-Elias coding is a good candidate since …
