this is my code for extraction of feature from folder having three sub folders but i am giving error at line trainingFeatures(featureCount,:)= ..... error is : Subscripted assignment dimension mismatch.
trainingFeatures = zeros(size(training,2)*training(1).Count,1008);
featureCount = 1;
for i=1:size(training,2)
for j = 1:training(i).Count
trainingFeatures(featureCount,:)= extractHOGFeatures(read(training(i),j));
trainingLabel{featureCount} = training(i).Description;
featureCount = featureCount + 1;
end
personIndex{i} = training(i).Description;
end

You may be getting this error because there may be different numbers of images in each imageSet. The easiest thing to do here is to make trainingFeatures a cell array.

You say size(training,2) indicating training is a 2D array, but then you later say training(i).Description indicating it's a 1-D array of structures. Before the loop, what does it say if you do this:
class training
whos training
size(training)

Sorry, I don't have the Computer Vision System Toolbox so I can't test anything with imageset variables. Perhaps Dima will answer.
