CORF uses as input the responses of center-on and center-off difference of Gaussians (DoG) operators. It achieves orientation selectivity by combining responses of DoG operators that are aligned in a colinear manner at a given orientation.
Besides orientation selectivity, the CORF operator achieves contrast invariant orientation tuning, cross orientation suppression and response saturation, typical properties of simple cells.

Added a condition which checks if the data.params is empty
Fixed a bug. The variable mem is now first initialised to [].
