Number of stages for cascaded pose regression

[umariqb]

Using the provided 'train_test.prototxt' file for training, how many stages for cascaded pose regression will be trained. Is there any parameter to vary the number of stages? Or does it only train the initial stage?

I think that there is only one stage. The algorithm trains the cnn model just once. The several stage approach requieres Image alignment as explained in the paper.
