Study Dip 24th Dayreproduced please indicate the source of this article: Http://blog.csdn.net/tonyshengtan, Welcome to reprint, found that the blog is reproduced in some forums, the image can not be normal display, unable to express my views, to this expression is very dissatisfied. Some sites reproduced my blog, very happy is that they write something more people see, but not happy is this paragraph was removed, also did not indicate the source of reprint, although this does not have the copyr

The input of a discrete Fourier transform (DFT) is a discrete set of values, and the output is also a discrete set of values. In the case of an input signal, the interval of the adjacent two sampling points is the sampling time TS. In the output signal, the interval of the adjacent two sampling points is the frequency resolution fs/n, where FS is the sampling fre

The following two-dimensional fast inverse Discrete Cosine transformation is based on the Code of Thomas G. Lane. It can be directly used for image or video processing. The test code is written by xuanjicang Yishi. // fidct.h void fidct(short *const block);void fidct_init(); // fidct.cpp /******************************************************************************* XVID MPEG-4 VIDEO CODEC* - Inverse DCT -** These routines are from Independent JPEG

" in multi-scale decomposition of image, such as the resolution of image as the scale of image decomposition, or the size of image object as the scale of image decomposition, or the parameter of convolution kernel for image convolution as the scale of image decomposition. 2 Image Two-dimensional discrete wavelet transformThe two-dimensional discrete wavelet decomposition and reconstruction process of image

OpenCV of Basic Learning Notes (15): Discrete Fourier transform This paper mainly introduces how to use OPENCV to carry on the Fourier transform of the image, its core function is the DFT (OPENCV). The technique of DFT is to map the spatial domain to the frequency domain, which plays an important role in image processing. Here we just get the result of its transformation and see what the poor-domain graph has. Development environment: opencv2.4.2+qt4

Although I have learned a lot about computer vision, I have never understood the mathematical meanings behind Fourier transform and image filtering. I am deeply disturbed by the existing formulas. Fortunately, through this internship at Huawei during this period, the basic knowledge related to digital signal processing has finally been filled in. The following are my learning achievements over the past few days, that is, my own understanding of Fourier transform. I.

Four or two-D discrete wavelet transformStatement: This article is my understanding of the wavelet, not guarantee correctness and rigor.Reference: "Digital Image processing" Gonzalez P3171. OverviewA two-dimensional scale function and three two-dimensional wavelet functions can be combined with a given scale function and a wavelet function:The f (x, Y) discrete function can be decomposed into a linear combi

Test instructions: For some colored dots, find the smallest rectangle, which exactly includes half of the red dots, and does not include the blue dots.Solving: Violence, seeking a two-dimensional prefix and, with the principle of tolerance to update. n is small so I used discrete optimization and ran a 0ms.Did not write two-dimensional prefix and, plus discrete write is not very skilled, so engaged for 2 ho

Understanding Discrete Fourier Transformation (4) ------ complex form discrete Fourier transformation uses the complex method very cleverly, making the Fourier transformation more natural and concise, it does not simply use the replacement method to use the plural, but analyzes the problem from the perspective of the plural, which is totally different from the real DFT. I, Returns the positive cosine of a n

Task Draws a three-dimensional surface with a given discrete point, for example to the following data: % x y z 1 2 3 1 5 2 2 3 4 3 8 5 ... Analysis 1. Data is not an interval grid data In this case, you cannot directly use functions such as mesh, surf, and so on, because these functions require a grid form for the data format, and each point is equal to the interval, like this: This is not the case (the actual rules can be seen in the following fi

The following code originates from http://blog.csdn.net/nuaazdh/article/details/7059630 and is slightly modified with "g++-O Bank bank.c" compiled under CentOS. Every time the system randomly generates 1, the current customer customer's counter is serviced by 2. The current customer and next customer arrival time interval, remember that these 2 points understand the entire code, the book is not very clear. The waiting time for each customer in the bank depends on the departure time of the previo

Recently in the chapter on the graph theory of discrete mathematics, here is my classification and summary of some important concepts of the graph. Describe the concept of relationships Association--used to describe the relationship between a point and an edge, which simply means that the edge is made up of those points and is associated with those points. The correlation matrix is a matrix that records the number of points in the Edge Association.

Perceptron is an early neural network model, presented by American scholar F.rosenblatt in 1957. Because the concept of learning was introduced for the first time in Perceptron, the learning function possessed by the human brain was simulated in a mathematical model based on symbolic processing, so it aroused a wide concern. The simple Perceptron model is still the structure of the M-P model, but it can gradually enhance the ability of the pattern division by using supervised learning to achie
