I want to train my support vector machine to classify human vs non human using matlab. In training phase am getting a large feature vector matrix around 1*335214 for a single human image. Is there a way to reduce the feature vector size or to select the location of human alone?
hy guys, I am doing a project on "Moving Human Detection using SVM in FPGA". Can anyone suggest me what kind of feature extraction algorithms can i use for training my classifier? still i dont have any idea to begin my project. Can anyone provide me some guideline?
Hy, Am doing a project in face gender classification using svm. 1.) could anyone suggest me the best feature extraction algorithm for this application? 2.) could anyone help me to find the distance between 2 points in an image using matlab? eg. distance between left eye to right eye?
what is actually a decomposition in signal ? what i get is that from a data of E(1) it goes to x(1)-x(n) composing that signal, where feature extraction is the act of extractng the data ? and class is when you get the data of the feature then it entered that classifier ? im still not very clear on this so please any help will be really appreciated
Hi I want to do feature extraction for a vibration data obtained from a beam specimen. Which method i can use to do it?? Is MFCC method suitable? Because, most of the MFCC applications are based on Speech Recognition.. If there is any specific method to do it, please let me know the step by step procedure... Thanks in Advance...

can any one have code for how to extract mfcc features from given speech sample
i work in speech emotion recognition i try to use this code it works will until i try to find the 30 coefficients or order of PLP can someone help me to solve this problem thanks
what kind of data you have. there are lots of features Morphological and discrete such as mean, Variance, RR interval etc. once you have data vector then you can proceed for features
Hi can any one help me to find out the features from speech . 1. Linear Predictive 2. Coefficients (LPC) 3. Linear Prediction Cepstral Coefficients (LPCC) 4. Mel-Frequency Cepstral Coefficients (MFCC) 5. First derivative of MFCC (dMFCC) 6. Second derivative of MFCC (ddMFCC) 7. Log Frequency Power Coefficients (LFPC) 8. Perceptual Linear
In signal processing, i did feature extraction using MFCC. then use kmeans(k=6) clustering technique to generate the i got 6 rows for each frame of data. but while testing i got 20 rows for each frame of data. because In Mel Frequency Warping, the number of mel cepstral coefficients,K,is typically chosen as 20. so i got 20 rows. After
I have work in matlab (gui) to recognize the image of beef and pork, was first performed with wavelet feature extraction meat haar and get the energy value of the meat... after then be obtained by using a probabilistic method of classification neural network (PNN) to determine whether the image of beef or pork? is there a source code gui matla
actually i am working on speech recognition ,I got stuck in between its coding about mfcc feature extraction and vector quantization so I need help related to this coding either give me an idea or give me the full code I am expecting fruitfull reply thank you

Please help me out with a matlab code for feature extraction in speech for emotion recognition in speech like sad, happy, bored, angry, neutral etc.
Please explain what DWT means. Could be "Discrete wavelet transform", "Dangerous world tour", "Driving while texting" etc. Forum rules say: don't use technical abbreviations unless they are universally understood. sir this is discrete wavelet transform.. and i would like to know how to do feature extraction of isola
Hi I want extract some features of GSR signal but for some feature i couldn't write Matlab cod if someone help me , i'll be so grateful . i need Matlab code for this features : GSR_freq : The total number of orienting responses of a segment for GSR GSR_mag : The summary of the startle magnitudes of orienting responses of a (...)
Hi, I have a project on fingerprint this semester, I want to do feather extraction based on texture in matlab.I want to use Gabor Filter Bank, but before I use this I should do orientation, find the core point and tessellate of circular region. Does anyone have code or any help for these 3 parts?
hi all i need matlab code for features exctraction using MFCC to use these featurs in dialect recognition
Hi; First you need to generate/extract some information from your images (here leaves i think). It is called feature extraction. You shouldn't supply raw data to NN. Otherwise it would be cumbersome. Good luck
im doin my final year project using matlab, the question is, after i record the data, what step i need to do, quite confusing, is it convert the data into wave file directly using matlab to do feature extraction. please help me. my data was a baby crying voice, if anyone dun mind can u tell basic steps that i need to do for this, a lot of thanks:-o
hello sir , i need a matlab code for speaker recognition using feature extraction as MFCC and feature or Pattern matching as ANN(artificial neural Network ) please do reply my email id is
Hi,I am doing a project on 'Detection on sleep stages using ecg'. I am in need of matlab code for extracting the time domain and frequency domain parameters for each 1minute segment of an ECG signal.Can anyone help with the code??? Kindly reply to this mail
You didn't tell which extraction nor LVS tool you're using. Usually LVS tools generate cross-ref (correspondence) lists for nets and devices. This is a feature which can be enabled (or not), see e.g. (Cādence si): si: simSetDef().... createXref is initialized to "nil". si: simSetDef().... useLastBinaryXrefTab

need MATLAB code for GLCM feature extraction from medical images , brain MRI images if any one has code of DCT feature extraction from medical images , do mail me at
There is no universal algorithm for feature extraction. The best way is to observe the signal (FFT in Your case) and select the features that are the most correlated with your classes. If You want to get some advice, You should write more information about Your problem.
I created a BPSK signal in Matlab and I'm wanting to extract the unwrapped phase from the instantaneous phase obtained. The detail is that the result will apply an equation to get the centered non-linear component of the instantaneous phase which is given for "phi_NL" in the code below. This nonlinear phase should be between a value close to zero a

feature extraction is a very broad subject area! Depending on your application, it might be good to focus on using scale-invariant, rotation-invariant, and illumination-independent features. Do you have a target hardware platform, software development environment, and programming language? Many of the relevant scientific papers are

Now when the tested signal is one of these signals, How do I set threshold value for these feature values to determine the (...)
As a first comment, classical harmonizer design did not use FFT. The first models used tape recorders with rotating heads, later this principle - replaying sound snippets with different speed - has been created electronically. Now, spectral processing using FFT, sound modelling and feature extraction is widely used e.g. in MP3 encoding and also
