I am working on classification of images using SVM classifier,
I want to do classifivation ,the dataset consists of males and females ,first i want to classify its gender,
if it is female i dont want to classify,if male i want to calssify it as adult or aged person
for this i have 100 images of males and females
i have extracted features like colour and texture and have saved in variable features
features =100x6,(100 images ,each column consists of feature vector),
features1 i have to test for 40 images(40x6)
so on whic basics i have to classify using svm classifier
please assist
svmStruct = svmtrain(xdata,group,'showplot',true); res= svmclassify(svmStruct ,te);
I get error in plotting,plz assist.

You have high dimensional data (in |R^6) and obviously you can't visualize 6 dimensions, so don't force the 'showplot' to true and you shouldn't see this 'Warning'
If you are concerned about visualization take the dimensionality reduction route and perform for example PCA and reduce it to 3 dimensions to visualize it.

thanks a lot for your suggestions walter,is there any demo for any images how classification is made,I want to know the concept of how classification is made
