Thank you for sharing this remarkable toolbox!
I've just installed the toolbox and run the bag_of_features.m, but unfortunately, en error was reported. It said that "Undefined function 'dltrain' for input argument of type 'struct'."
Error in extract_bag_of_features (line 229)
D(: , : , s , c) = encoding(X(: , indexdico) ,
Could you please so kind to help me with this little problem? I am really an new hand in this area...
