Huffman codes In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0’s and 1’s? To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. This problem can by solved by using an extended binary tree which is used in the 2- way merging problem.

摘 要 文章以空間監控系統為背景,深入研究了JPEG圖像壓縮標準的實現方法,并基于FPGA對其進行了實現和優化。文中給出了詳細的實現方法和優化過程,測試表明達到了很好的效果。 簡單介紹了有損靜態圖像壓縮當前有兩種比較流行的標準JPEG和JPEG2000。說明了用JPEG方法壓縮的原因。 介紹JPEG基本原理：JPEG對灰度圖像的壓縮處理過程主要包括:圖像分割,離散余弦變換(DCT),量化(Quantization),“Z”形排序(Zigzag Scan),差分脈沖編碼調制(Differential Pulse Code Modulation,DPCM)對直流系數(DC),行程長度編碼(Run-Length Encoding,RLE)對交流系數(AC),霍夫曼(Huffman)編碼等。 JPEG標準的特點是離散余弦變換。 比較詳細介紹壓縮系統的構成和實現。實現提及步驟， JPEG壓縮模塊設計和編碼模塊實現細節。

Huffman codes 1.In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0 s and 1 s? 2.To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. 3.This problem can be solved by using an extended binary tree which is used in the 2-way merging problem. the sourse code is to encode and decode the Huffman.

) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.

C++ From Scratch: An Object-Oriented Approach is designed to walk novice programmers through the analysis, design and implementation of a functioning object-oriented application using C++. You will learn all the critical programming concepts and techniques associated with the language in the context of creating a functioning application. Best selling C++ author Jesse Liberty shows you how to create "Decryptix", a game of decoding a hidden pattern as quickly as possible, using nothing but successive guesses and the application of logic. Every example and technique is put into the context of achieving a goal and accomplishing an end.

Yet another mp3 player, but this time using SVGALib under Linux. The idea was to use a 320x240 display which can be used in a vehicle. I wrote this quite a few years ago, before mp3 players were so cheap. It uses mpg123 for the mp3 decoding.
