Arithmetic CodingIt is a lossless data compression method and an entropy encoding method. Unlike other entropy coding methods, other entropy coding methods usually divide input messages into symbols and encode each symbol, the arithmetic encoding directly encodes the entire input message into a number, which is equal to or equal to 0.0.N

(reprint) Common Audio Protocol IntroductionIntroduction and comparison of common audio protocols for conference TV white PaperFirst, the digital audio principle: The sound is actually a kind of energy wave, therefore also has the frequency and the amplitude characteristic, the frequency corresponds to the time axis, the amplitude corresponds to the level axis. Usually the ear can be heard in the frequency of 20Hz to 20KHz of sound waves known as audible, less than 20Hz to become infrasound, hig

Is it a little confusing? Today, I'm going to introduce you to Zen coding, a set of tools for fast HTML and CSS encoding. Originally introduced by Vadim Makeev in April 2009 (the article in Russian), I developed a few months from my humble (i.e. I) and finally reached a more mature state. The Zen coding consists

Intra-frame prediction of predictive coding (intra-picture prediction)Predictive coding (prediction Coding) is one of the core techniques of video coding, which uses one or several coded sample values to predict the current sample values according to a model or method, and encodes the difference between the real and pr
The overall overview of the implementation process of the genetic algorithm is as follows:
1, choose the coding strategy, convert the parameters into strings;
2, according to the population size n, randomly produces n string composition of the group;
3, according to the fitness function f=f (x) to calculate the fitness of each string;
4, according to the replication probability of the string f=f (x) Select a string to replicate, until already copied n

The coding methods and problems of win, PY, notepad++ first to say the conclusion:
Because the default encoding used by Win CMD is GBK (ANSI), if it encounters bat or Python's Chinese needs to be displayed in cmd, if garbled, first check whether because it is not 1. GBK encoded in Chinese or 2. is converted to GBK encoding or 3 in code. In Python code, it is a Unicode object .

Inter-frame prediction of predictive coding (inter-picture prediction)Inter-frame prediction refers to the use of video time domain correlation, using neighboring encoded image pixels to predict the current image of the pixel, in order to effectively remove the video time domain redundancy. Since the video sequence usually includes strong time-domain correlation, the predicted residual value is close to 0, and theresidual signal is transformed, quanti
The basic method of entropy coding in the first and H:
Entropy coding has the function of eliminating statistical redundancy between data, and the syntax element is written to the output code stream as the last operation in the coded end.
Entropy decoding, as the first step in decoding process, parses the code stream into grammatical elements for subsequent steps to reconstruct the image using
about the historical evolution of the code, UTF-8 is how to develop, why Windows still keep GBK encoding ...
And so on, online a search a lot of, most of them are forwarded, share after the same content, still can not solve my inner doubts ...
Coding is a matter of egg pain, if not clear, how to mix in China?
I have set a basic world view of coding by looking through multiple documents and in-depth
average bit number of information contained by all symbols of the source.
Source Coding should minimize the redundancy of the source to bring it closer to entropy.
Transmit more source information with fewer bits
Entropy Coding: minimizes the entropy of a message based on the probability model of the message source in data compression.
Lossless Compression
Variable-Length Encoding
Information Interchange, American Information Interchange standard codes) is a computer coding system based on the Roman alphabet.
2. Features
It is mainly used to display modern English and other Western European languages. It is the most common single byte coding system today and is equivalent to ISO 646.
