20080218594 | Differential Phase Correlation - Acceleration of a set of three frames of video with N movers may be determined by generating an inverse Fourier transformation of a differential phase correlation matrix of the three frames. The resultant acceleration estimate may be integrated with the velocity and offset estimates for the second frame so as to provide an offset estimate for the third frame. The third frame may then be co-registered with a reference frame. This process may be repeated for subsequent frames so that subsequent frames may also be registered to the reference frame so that video jitter that was caused by platform shake may be reduced or eliminated. | 09-11-2008 |
