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

Today, we are pleased to announce that Coding Enterprise released--coding Enterprise is Coding Enterprise-specific software development collaboration platform, providing a public cloud version for SMBs and a private cloud version for large enterprises. Functionality covers all development scenarios, enabling organizations to develop and collaborate more efficient
The target application of H. E covers most of the current video services, such as cable TV remote monitoring, interactive media, digital TV, video conferencing, video on demand, streaming media services. To solve the difference of network transmission in different applications. Two layers are defined: The video coding layer (Vcl:video Coding layer) is responsible for efficient video content representation,
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
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
This is the HEVC coded frame diagram, and I'll write down my own understanding of the HEVC coding process for this diagram. (A lot of mistakes, in the rookie stage, look at the peer of this article can give some advice, I will be greatly appreciated)
In the diagram, you can see that there are several clearly interconnected modules. Coding control, transformation quantization, inter-frame prediction (motion
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
ObjectiveHDFs can also support the Erasure coding feature, which will be released in Hadoop 3.0 and can be validated by the diagram:In HDFS-7285, this new feature is implemented. Since this feature is far from the release stage, it is possible that the code behind this block will be further modified, so just do a so-called pre-analysis , Help you get an idea of how the Hadoop community is doing this right now. I have not been exposed to erasure
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.
3. Include content
Control characters: Enter, backspace, newline keys, and so on.

There are many children in China who are 18, 9 or years old. They have also written a lot of code through self-study. Some of their code is very beautiful, some technical details are quite outstanding, and they are also very diligent, however, they are influenced by some wrong understandings and opinions, and lack the a
