matrix structure is as follows. (A two-dimensional plane uses a matrix of 3x3 in the same principle ). Each element in this structure is given a number, and the code of the number represents the row and column respectively. 4.Transformation Calculation Formula A matrix can be used for vector and point transformation operations. A coordinate or vector and a 4x4 matrix can be used for point multiplication and conversion. You can use a column matrix o

Take the 4 Queen as an example, the other n Queens question and so on. The so-called 4 queen problem is solving how to put 4 queen pieces on a 4x4 chessboard without conflict. In chess, the Queen moves in a horizontal and vertical way, so that no Queen's pieces can be seen at the level, upright, or 45-degree slash of any queen's position, for exampleRequires programming to find out the number of cases that meet the requirements. There are a number of

Corresponds as shown.Figure 1 HEVC three ways to scanDepending on the mode, use one of the three ways: horizontal, vertical, diagonal. For blocks that exceed 4x4, the blocks are first divided into several 4x4 CG (coefficient Group), and

AES (Encryption Standard, Chinese: Advanced Encryption Standard), is a block encryption standards. AES is processed by dividing the raw data into multiple 4x4 byte matrices, with a pre-defined key that makes each byte in each byte matrix XOR, replaced, shifted, and linearly transformed to achieve the purpose of encryption. The key length can be 128,192 or 256 bits.Here is an example of using the Python M2crypto library and using the AES_128_ECB algori

(Nal:network abstraction Layer) is responsible for packaging and delivering the data in the appropriate manner required by the network. The motion vector of 1/4 or 1/8 pixel accuracy is supported. A 6-tap filter can be used to reduce high-frequency noise at 1/4 pixel accuracy, and a more complex 8-tap filter can be used for motion vectors with 1/8 pixel accuracy. The encoder can also select the "enhanced" interpolation filter to improve the pre-measured effect when motion is expected. There are

4x4 matrix.The following 5 types of operations are described.1.1 bytes insteadThe main function of byte substitution is to complete the mapping of one byte to another through the S box. The detailed construction method of S-box can be referenced in reference [1].(a) for S box, figure (b) is S-1 (inverse of S box).S and S-1 are 16x16 matrices, respectively. Assuming the value of the input byte is a=a7a6a5a4a3a2a1a0, the transformation with the output

Normal convolution operation: As pictured above: 4x4 input, convolution kernel for 3x3, output for 2x2. The calculation can be understood as:The input matrix expands into a 4*4=16 dimension vector, which is recorded as XThe output matrix expands into a 2*2=4 dimension vector, which is called YThe convolution kernel C is the following matrix:The convolution operation can be expressed as Y = Cx (which can be understood by the motion diagram), and the r

Adam Harley made a very stunning convolutional neural network visualization, which was trained with the mnist handwritten digital database. I strongly recommend that you play a game in order to understand the details of convolutional neural networks in greater depth. Below we will see how the network recognizes the input number "8". Note that the Relu process is not shown separately in figure . Figure 18: Visualization of convolutional neural networks The input image has 1024 pixels (32x32 pict

Block effect and its causeWhen we watch the video, in the scene of vigorous motion, we can often observe that the small squares appear in the image, and the small squares show discontinuous effect at the boundary (such as), this phenomenon is called the Block effect (blocking artifact).First, we need to figure out why the block effect occurs. In the coding process, the DCT transform of the pixel residuals was obtained, and the DCT coefficients were correlated with each pixel, which represented t

I. texture filtering: When the polygon in a 3D space changes to a set of pixels on a two-dimensional screen through coordinate transformation, projection, raster, and other processes, each pixel needs to be sampled in the corresponding texture image, this process is called texture filtering. Ii. texture filtering is generally divided into two types:A) The texture is reduced to gl_texture_min_filter.For example, if an 8x8 texture is attached to a square parallel to the XY plane, the square occupi
