Data is saved in the same location as the images, as alex.dat, or whichever name was provided to the collect_data function. This contains a structure called s, which looks like this:

         id: 'alex'
    lastimg: 'SURFBOARDS-COVER.jpg'
       data: {[1x1 struct]  [1x1 struct]}

The data within s is a single rectangle:
