I'm having a big troubles with the libraries that I have to use in my project . whenever I tried one of the libraries , a problem appears and I don't have so much time to get lost for all this time :( my project is "Image Understanding" so I need a "feature extraction" & "image segmentation " & "Machine learning" after reading , it turned out the " SVM " is the best one and I want some code to build mine on it and start off .

1- first I looked at "Aforge & Accord" and there was an example named "SupportVectorMachine" but it's not on images .

2- I found a great example in "EmguCV" named "LatentSvmDetector" and it detected any image of cat I tried it !! but the problem was in the xml file ! I just wanted to know how they got it ! and I couldn't find a simple answer actually I asked you here and no body answers me :(

[link] How to extract features from image for classification and object recognition?

3- I found an example uses opencv here in this site

[link] http://www.di.ens.fr/~laptev/download.html but the same problem : xml file ?!!! I tried to take the xml file of this example and tried in the "EmguCV" example but it didn't work either .

4- in all the papers that I read they're using "ImageNet" & "VOC PASCAL" , I downloaded them and they're not working !! errors in the code of the tool !! and I've fixed them all but yet they're not compailing , those tool are written in "Matlab" here's my qusetion on this site : [link] Matlab Mex32 link error while compiling Felzenszwalb VOC on Windows for god sake can anybody tell me what should I do ?! I'm running out of time , need your help ! thanks.

I'm not sure, because I never used SVM (but used haartraining) but I think that they have trained the detector using a program that outputs a xml file at the end of the training. I have made a quick search and found this link (opencv doc about svm training) and this link (a post with a example). I hope that it helps you and give some light.

  • actually the example you gave me is exactly what I need ! but I'm still having problems with it , because of the " cmake " can you help or I have to post another question for it ? – SafeY Mar 16 '12 at 17:32
  • Which problem you have with the cmake? If possible, please show the output. I'll try to help :) – cyberdecker Mar 16 '12 at 22:00
  • I post it as a question here [link] http://stackoverflow.com/questions/9742052/cmake-is-not-working-in-opencv-c-project/9743635#comment12394012_9743635 – SafeY Mar 17 '12 at 13:45

MATLAB supports xml files - both reading and writing. Try: 

 xmlfile = fullfile(matlabroot, 'path/to/xml/file/myfile.xml');
 xDoc = xmlread(xmlfile)

If you don't have xmlread function they you can try this toolbox: http://www.mathworks.com/matlabcentral/fileexchange/4278-xml-toolbox

  • It's not a reading problem but I'm asking if anyone knows how they got it in all those tools ? – SafeY Mar 11 '12 at 11:39
