I decided to use a strong combination of objective function and see if it still performs well when faced with a different set of data. The settings for the experiment were the same as in 2.1, but instead of using the same data, several different datasets are taken into consideration. ssd was used as the shape OF (objective function) and def_energy as the intensity OF.
Conclusions: This result means that the parameters were not adjusted only to fit a certain couple of images.
