Textbooks are usually given here and then left to the reader endless reverie, and endless spit groove, in fact, as long as the textbook to fill a picture is enough: frequency domain image, known as the spectrum, is-- A little clearer: It can be found that in the spectrum, the amplitude of even-numbered items is 0, which corresponds to the color line in the graph. Sine wave with an amplitude of 0. To be honest, when I was studying the Fourier transform, t

different distributions of black and white pixels in the matrix. In the position of the corresponding elements of the matrix, the presence of dots (square dots, dots, or other shapes) represents the binary "1", and the presence of the dots indicates the binary "0", and the permutation and combination of the points det

method, RS coding is simple, is to first know how much I need to have the error correction codeblock, and then construct a polynomial with this number: (x-a^0) (x-a^1 )... (x-a^n-1), where a, or alpha, is the base in GF256, A^n-1 represents a GF256 finite field element, where n is the number of error correction codeblock, and then the data to be encoded codeblocks form a similar polynomial, The value of each codeblock is the coefficient of the polynomial, from high to low, with this data polyno

this article, as mentioned in the IQ article, uses only 4 octave.Now, the first step is to create these octave first.Creating a noise textureThe first step is to create the individual octave that make up the fractal noise. and "graphics" talk about noise a little bit differently, because we need to constantly translate these textures, in order to achieve seamless connectivity, we need to make these noise textures seamless (seamless). To get a seamless 2D noise texture, the usual method is to fi

The binary lookup tree (Binary search Tree,bst) is a two-pronged tree (from a wiki) that has the following properties: 1 if its left subtree is not empty, the value of all nodes in the left subtree is less than the value of its root node; 2 If its right subtree is not empty,

However, some people do not know why I need to insert a DVD disc to install the software, because the DVD is added to the source list as the local source by default. If you do not need it, you can deselect the "cdrom: //" source in "software library" settings. However, we recommend that you retain the software because the Debian DVD contains a lot of software. Among them, DVD 1 is the most common software. to configure basic desktops, you must cap

If you do not need to, you can uncheck the cdrom://source in the "Software Library" settings. But personal advice to keep, because the Debian DVD contains a lot of software, DVD 1 is the most common software, the configuration of the basic desktop needs to be installed from the DVD 1 crawl package.

Date: 2014-10-31The code structure of the Datamatrix is basically the same as the QR code:The function of detector is to find out the part of the symbol code from the original image, and make the perspective transformation to correct the distortion. The decoding process is similar to the QR code, and the key is how to remove the real symbol image from the original image. As stated above, the Perspectivetransform method in the digital Image warping written by George Wolberg can establish a mappin
