The NCC is one of the basic and popular statistical approach used for image registration. It is widely used for template matching and pattern recognition. NCC is utilized as a metric to assess the level of dissimilarity or similarity between two signals or digital images. It is also advantageous over the ordinarycross-correlation because, it is robust to linear changes in the illumination amplitudes in the two compared images. Furthermore, the NCC is confined in the range between 1 and -1. The setting of detection threshold value is much simpler than the crosscorrelation. Mathematically the NCC is given28 as equation 1:
