I do not know how to create a training set from images & learning through R or matlab.
1. Select some features from the hyperspectral image like calculate gradient
2. With that value make a feature vector for the positive and negative images
3. store that feature vector into a file .csv or .dat format
4. select the classification algorithm like SVM or something else
5. make a model with the training set
6. test that model
For use SVM or Support Vector Machine you need training matrix and group matrix
note : Svm support two group , e.x group 0 and group 1
First : calculate some feature for training matrix
Second : Design matrix group
Third : after step 1 and 2 you tarining svm how ?
svmstruct=svmtrain(training,group, ...
'Autoscale',true, 'Showplot',false, 'Method','QP', ...
'BoxConstraint',2e-1, 'Kernel_Function','rbf', 'RBF_Sigma',1);
forth : after step third you test your algorithm how ?
GROUP=svmclassify(svmstruct,sam,'Showplot','false');
if GROUP==0
disp('***************');
else
end
Please suggest some feature for spatial and spectral classification
I need to develop 3D bandlet transform for the hyperspectral image compression. I need to know how to develop the same @ matlab.
