A game you often play when you are a child:Complete the game by moving only the small squares around the space and eventually moving all the blocks to the target locationThe logic of the program is not difficult:1. Initialize all (4x4) button properties (position, size, label, whether visible) and methods (click Button Exchange), and arrange them sequentially2. Click Shuffle to start the game (by randomly swapping any of the two buttons x times)3. Eac
LAN is required, mainly to design a 5 GHz spectrum allocation-using a wider 40 MHz and 80 MHz channel, they require a higher data transmission rate. In the short term, a small number of 11ac access points serving 11ac and traditional clients are scattered, and it is unlikely to occupy the backend network infrastructure. In addition, these access points can be integrated for existing 1 Gbps Ethernet connections and Ethernet power supply (PoE ).
However, with the upgrade of the 11ac standard clie
specific direction and runs independently without any other client devices generating traffic? The answer is self-evident. No.
Cost is always king
From a business perspective, it is hard to believe that someone is willing to spend money on reaching the 10GbE edge for all access points, and no one is willing to spend money on Cat7 cabling of a higher level (to be honest, Cat 6 may be more reasonable ). It is clear that the cost of deploying multiple copper cables for each access point with Link
-dimensional, we want to get a three-dimensional vector. (If you can really get a four-dimensional vector, you do not dare to turn around at home, turn round, entered four times!) Then the left multiply unit four, right multiply its conjugate operation to ensure that the result is a three-dimensional super-plane in the pure four-dollar number.The expression of the left and right multiplication as matrices will let us see more clearly. According to the definition, the matrix form isObviously, the
Since unity has only a 4x4 matrix, today is going to do a 2x2 matrix rotation and actually forget the order. So write down as a template record.Order:The following is the C # code that you use to rotate it: Public structposition{ Public intX; Public intY; Public Override stringToString () {return "X:"+ X +"Y:"+Y;}}voidOnenable ()//Execute{ varPosition =NewPosition () {X =1, Y =0 }; varAnchor =NewPosition () {X =0, Y =0 }; Debug.Log ("Position:"+
, when the selected P is much less than N, the smaller the amount of information to be stored, achieving the goal of dimensionality reduction and compression.
Application of PCA image compression:
Procedure:
1. Divide the input image into 4x4 16-dimensional blocks.
2. Construct a matrix of observed sample data. Each column is a block and each column is a 16-dimensional data matrix.
3. Calculate the sample covariance matrix.
4. The sample covariance ma

The former is used to reduce the entropy value, and the latter converts the data into an effective encoding method that can reduce the number of bits. In the MPEG standard, the conversion encoding adopts DCT. Although the conversion process does not compress the bit rate itself, the converted frequency coefficient is very helpful for bit rate compressio

1. H.264 new feature learning stage
First, we learned the classic document about H.264 overview in Weigand, which covers most of the new features of H.264. Afterwards, we held three meetings to further learn the new features of H.264 in groups.
The content of the inter-frame encoding team is as follows::High-precision motion estimation,The semi-pixel point interpolation prediction and 264 pixel point interpolation prediction of H.264 are analyzed.And also analyzedInterpolation prediction of H.26

The B Macro Block uses two-way reference images (current and future encoded image frames) for intra-frame prediction.
Now we can easily understand the encoding functions available for each grade. For example, in the video session system, we can only get th
