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

1. Setting items that affect Chinese encoding Encoding (ENC): encoding is the internal use of Vim code, encoding settings will affect the internal vim buffer, message text and so on. In a UNIX environment, the default setting for encoding is equal to the locale;windows environment and the current code page. The default setting for encoding in the Chinese Windows environment is cp936 (GBK). FileEncoding (Fencs): Vim is saved when the new file is saved according to the fileencoding se

The default encoding for the new project for Eclipse is UTF-8 directly:In the menu bar,Window->preferences->general->workspace->text file EncodingChange it to UFT-8.This modification is only valid for the current workspace, and if you create or switch to a new workspace, you still have to do the same.Same Window->preferences->general->content TypesYou can modify the default encoding for files in different formats,In particular, html,css,javascript files such as encoding is best modified,Otherwis

Describe two lines in the following code #The first line of comments is to tell the Linux/os x system that this is a python executable and the Windows system ignores this comment;The second line of comments is to tell the Python interpreter to read the source code according to the UTF-8 encoding, otherwise the Chinese output you write in the source code may be garbled.#!/usr/bin/env python#-*-coding:utf-8-*-print u ' Chinese test normal ' print '----------------------------------------------'

not a message at all.2) general product Code (UPC, commonly known as: bar code, is also a binary code, consisting of 30 vertical stripes of different widths, decoded by 12 digits, below the stripe; it is a 95-bit binary code that contains left guard line, digital, middle guard, digital, right protection line. The first number is the number system character, 0 is the regular UPC, the next five digits are the manufacturer code, the last five bits is the product code, the final number is the modul

words.Therefore, in the spirit of saving, there has been the conversion of Unicode encoding to "Variable length encoding" UTF-8 encoding. The UTF-8 encoding encodes a Unicode character into 1-6 bytes according to a different number size, the commonly used English letter is encoded in 1 bytes, the kanji is usually 3 bytes, and only the very uncommon characters are encoded into 4-6 bytes . If the text you want to transfer contains a large number of English characters, you can save space with UTF-

time-Read the code without looking at the function declaration for I/O at a glanceThe above is still a high degree of readability, but also can quickly locate the issue of compile time.Of course, it is difficult and unnecessary to consider these details in actual team development, but it is possible to understand the tastes and logic of a person. The quality of the code is really not particularly related to the success or failure of the product and the company, but as an engineer, we should pur
