inlinevirtual

Given the pixel co-ordinates and an offset values, this returns the value of the convolution function.

This is however not used anywhere yet (and is therefore also not a pure virtual function).

This method computes the average response function.

This is typically image-plane equivalent of the convolution functions, averaged over various axis. The precise averaging will be implementation dependent in the derived classes.
