With a device for a lateral containment of liquid steel between two crystallizing rolls of a casting machine for a steel strip, comprising a refractory skid and a thrust unit for the skid. The method provides an input signal, and generates an output signal. Each signature vector is composited into multiple portions from the plurality of signature vectors to define an appearance-invariant signature of the graphical object.
