same time to increase the number of one-dimensional computation = =One of the main forces in representing linear transformations with matrices is the ability to easily combine transformations and inverse transformations. Combinatorial transformations: Combinations can be accomplished by matrix multiplication.

In H.264, Rate Distortion Optimization plays an important role.Formula for rdo: J (mode) = SSD + λ * R (ref, mode, MV, residual)SSD refers to the mean square sum of the difference between the reconstruction block and the source image, and λ is the Laplace multiplier;R is the actual bitrate of Macro Block encoding in this mode, including the bit rate of the reference frame, mode, motion vector, and residual.Of course, only R (mode, residual) is supported ).However, because SSD needs to reconstruc

be a big headache for the compiler to recognize hexadecimal notation, I think this should not be a problem for Real programmers. To put it bluntly, you must make your own efforts to solve any problem, rather than simply asking others if you do not analyze it. That way, a person will never grow. It is sometimes necessary to seek help, but not the most critical .)　　4.2.4 Vector Matrix Multiplication　　We often need to multiply a 4x4 matrix by a vector.

implemented through matrix operations. Specifically, when a conversion command is issued, this command will generate a 4x4 transformation matrix (the object coordinates in OpenGL are always homogeneous, that is, (x, y, z, w ), therefore, all transformation matrices use a 4x4 matrix). The current matrix is multiplied by this conversion matrix to generate a new current matrix. For example, for vertex coordin

, B3, A3R4, G4, B4, A4}When we combine this matrix with another 4x4 matrix m{RR, GR, BR, arRG, GG, BG, AGRB, GB, BB, ABRa, Ga, Ba, AA}When a matrix is multiplied, a new matrix is generated. The number of elements in the new matrix is the same as that in the original matrix. (If you do not believe this, use the [5, 4], [6, 4] matrix to multiply it ), in addition, every element of the new matrix has undergone interesting changes. Let's take a look at th

. 3dfx adds a 2x2 or 4x4 anti-aliasing effect to the driver. Based on the serial chip, the dual-chip voodoo5 provides a 2x2 anti-aliasing effect, the four-chip card can provide a higher 4x4 anti-aliasing level. In short, it is to mix the image edge and the pixel colors on both sides, then, replace the points at the original position with the newly generated points with mixed characteristics to soften the sh

Statement: ThisProgramIt is not used for commercial purposes and is only used for technical learning. Around the world, Xiaomi notes feature powerful interface appearance, called the android most powerful notes program. With a learning attitude, I tried to write it and try to restore the interface of the original program (using some pictures in the original program) and its functions. However, due to time reasons, some functions were not implemented. In addition, I added support for simple

* A11) 10) inverse of the matrix Definition: For matrix A, there is a matrix A-1 that makes a * A-1 = I, then the A-1 is the inverse of matrix. In fact, this A-1 is a multiplication inverse element. There is also a saying in mathematics: If a n × n matrix does not have a multiplication inverse element, it is called a strange matrix. His role is very important, such as the equations mentioned above: A * B = C, matrix B By multiplying the two sides of the equation by the A-1, then: (A-1 * A) *

coordinates (x, y) are determined in this way. x starts from left to right, starts from 0, and y starts from top to bottom, this is the most common coordinate system in image processing: ----------------------> X|||||∨ Y If you want to enlarge this image to a 4x4 image, what should you do? The first step is to first draw the 4x4 matrix. After the matrix is ready, it is shown as follows. Of course, each pix

computers can zoom in and out images. In this article, all images refer to bitmap, that is, a pixel matrix to describe images, for another image: using functions to describe the vector image is not discussed in this article.The simpler the model, the more suitable it is for example. Let's take a simple image: A 3x3 256 grayscale image, that is, a 3 pixel High, the width is also a three-pixel image. The value of each pixel can be 0-255, indicating the brightness of the pixel. 255 indicates the b
