, 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

Brief description of YUV color format 1 cause 2 root causes 3 Comparison 4. Reference Introduction YUV Color format -- Starting from the problem of color skewness in Xvid Decoding (Chen YiChuan ybc2084@163.com UESTC, Cd) 1Cause The reason was that two weeks ago, when I decoded a MPEG-4 code stream with Xvid, I found that the decoded video sequence was blue. The color field space specified at that time was yv12. I remember that yv12 is in the yuv4: 2: 0 color format. But

transformation (Viewport transformation) (In the screen window can define a rectangle, called the viewport (Viewport), The graphics shown in the viewport are displayed in the viewport, and the scope and dimensions of the scene are shown on the screen.Through the above steps, an object in a three-dimensional space can be represented by a corresponding two-dimensional plane object, and it can be displayed correctly on a two-dimensional computer screen. In general, the display of three-dimensional

3D objects Ii. Several transformations in OpenGL Various conversions in OpenGL are 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

information (CRC code), the remainder of the generated polynomial should not be 0 after the modulus 2 is division. C. When an error occurs for different bits, the remainder should be different. D. Perform the division of the remainder by mod 2. The remainder should be cyclically generated. Reflecting these requirements as mathematical relationships is complicated. However, the commonly used generative polynomials corresponding to different code systems can be found from relevant data, as shown

the +x axis, above the +y axis, the direction of view is the z-axis. Thus the observation space is a right-hand system. In the object observed by the camera, the object z in the distance is smaller. The question now is how we can transform the coordinates in world space into view space. Obviously, this is an affine transformation, consisting of a linear transformation and a one-time translation. The 3x3 matrix can only describe linear transformations, and for the sake of unification, homogeneou

coordinate transformation, the projection coordinate transformation, these series of coordinate transforms if uses the matrix, can complete all coordinates transformation processing in a matrix. Anyway, why the matrix is so important, you should probably understand it. Mainly, the calculation efficiency of matrix is very high, and it is convenient.3D Rendering and matricesIt says that matrices are combined by numbers, so what is a matrix?Although there are many kinds of matrices, one of them is
