How to get image response from Neural Network training image?

mmc01

I'm new for matlab, I tried to study tracking object with Neural Network from this thesis http://www.waset.org/journals/waset/v6/v6-50.pdf After I train image with newff and plot value it show only graph, I don't know how to get coordinate from neural network.
And when I try to use neural network image recognize. I can show graph from result traning only. I don't know what image response of traning neural network. please show me some example or describe me how to show image response from traning.
