Huffman coding is a method of data compression that is independent of the data type, that is, the data could represent an image, audio or spreadsheet. This compression scheme is used in JPEG and MPEG-2. Huffman coding works by looking at the data stream that makes up the file to be com...
Even though there are so many compression technique already presents and have better technique which is faster, memory efficient and simple, and friendly with the requirements of the user. In this paper we proposed the method for image compression and decompression using a simple coding technique ...
DEEP COMPRESSION: COMPRESSING DEEP NEURAL NETWORKS WITH PRUNING, TRAINED QUANTIZATION AND HUFFMAN CODING:用剪枝、训练量化和霍夫曼编码压缩深度神经网络 这篇论文是Stanford的Song Han的 ICLR2016 的 best paper 1 Abstract 论文想解决的问题? 神经网络的计算密集性以及内存密集性使得其在嵌入式设备上难以部署 论文...
Under the environment of Windows XP,compression/decompression of data file by adaptive HUFFMAN coding is realized with Micosoft Visual C++6.0 in this paper.All the process of coding and decoding is dynamically completed and the HUFFMAN coding tree is not needed in the compressed files. ...

/*** This is an implementation of Huffman coding.** The core algorithm is taken from the CLR book (Introduction of Algorithms),* Chapter 16.3, and directly used to implement the 'build_tree()' routine.** After the tree is built, a code table that maps a character to a binary* code...
