MATLAB Image Processing _ Fourier transformation, matlab Fu Li Use relevant functions such as fft in matlab. The Code is as follows: Clear‑clc‑img‑imread('test.jpg '); img = rgb2gray (img); f = fft2 (img); % Fourier transform f = fftshift (f); % symmetric image r = real (f ); % calculate the real part I = imag (f) of the image in the frequency domain; %

The method of random disturbance of training samples in matlab, matlab Samples Use randperm () to generate random seeds, and then swap locations for random sample extraction. Official content: The built-in function randperm (n) of Matlab generates random orders of integers ranging from 1 to n without duplicates. Then, we can use it to obtain random numbers withou

The P file is a pre-parsed version (preparsed version) corresponding to the M file ). Because when you execute the M file for the first time, Matlab needs to parse the file (PARSE) Once (the parsed content after the first execution will be placed in the memory for the second execution, that is, the second execution does not need to be parsed), which virtually increases the execution time. So we will explain it in advance. When we use the M file later,

MATLAB Image Processing _ homomorphic filtering, matlab Image Processing homomorphic Homomorphic filtering: uses the generalized superposition principle to filter the homomorphic system. Homomorphic filtering is an image processing method that combines frequency filtering and grayscale transformation. It relies on the image illumination/reflectivity model as the basis for processing in the frequency domain,

Matlab reads 3D point cloud data Stanford rabbit, matlab Stanford Where the point cloud data is Stanford rabbit. After the 3D point cloud reconstruction, people can take a good look, but simply read the program. As a beginner, it is better, and further research is still behind, if you have the opportunity to continue uploading, for example, delauny triangle mesh division, you also want to further study the

The process simulation system of WEDM (WEDM) based on BP neural network needs the design function of process database management, process effect prediction and processing parameter optimization. With the help of MATLAB's Neural network toolbox, we can set up good prediction model of process effect and parameter optimization model, which is the main function requirement of process simulation software. VB is an excellent visual programming tool software under Windows operating system, which has un

(Promotion by friends) Proficient in Matlab GUI Design (including one CD) coming soon IntroductionThis book describes the Matlab GUI Design step by step from a practical point of view based on the actual needs of Matlab Application Teaching and Engineering Application in colleges and universities, and uses a large number of design examples and typical application

://ishare.iask.sina.com.cn/f/37004900.html. Because FRR and far conflict with each other, the probability of equal error rate is equal when the two are equal. When the threshold is th, the corresponding FRR has a value and far has a value. In this way, a group of corresponding FRR and far are obtained. The far is used as the horizontal coordinate, and the FRR is used as the vertical coordinate to draw the curve, that is, the ROC curve. Then draw the Y = x curve. When the two curves intersect, th

This paper introduces the debugging method of DSP Application Based on MATLAB based on specific examples. MATLAB has powerful analysis, computing and visualization functions, using dozens of professional toolboxes provided by MATLAB, algorithm Analysis and Simulation for automatic control, signal processing, and communication systems can be conveniently and flexi

A few times ago a number of users asked how to use WASPCN (water and Steam properties calculation software) in 64-bit MATLAB, has not been able to give a solution.A recent project has also needed to solve the problem by using WASPCN (water and steam nature calculation software) in 64-bit MATLAB. The whole process is really not easy. Need to first modify the original WASPCN.dll 64-bit version of the DLL, b

Some time ago to explore the Java invoke matlab things, do not say how deep the study, also counted the results, to achieve the purpose. The Java program is also used to invoke functions in MATLAB. In order to say it, the beginning must be the next MATLAB to see. Which one is next. Starting with the next 7.0 feels very new. Later I thought it was not, and now th

I have not seen the MATLAB has a class dict structure, this can not but say is a kind of regret. Of course, this superficial understanding, also let me earlier and Julia knot the fate, gain it. From 2010 to 2013, I was mainly using MATLAB, such as DataSet (=>table) and other data structures (Matrix, cell,struct). Recently saw a lot of people in writing related articles, specially turn, for
