| 英文摘要 | Global translation preferred active contour is much more suitable for object tracking.The prior information of active contour with global translation preference can be interpreted as the velocity field along the evolving contour with equivalency preference.According to this,a simple gradient flow which preferes global translation is acquired by defining a new inner product on the set of perturbations of a curve.The new inner product is obtained by adding the variance of the perturbation of a curve to the inner product relative to the H0 active contour.The active contour relative to the new inner product is called variance active contour.In contrast to H1 active contour generated by convolution of H0 active contour and certain kernel functional,variance active contour needs no convolution and is a weighting sum of H0 active contour and corresponding average gradient flow.Thus,variance active contour can be implemented much faster and easier than H1 active contour.We also compared H0,H1 and variance active contours in space and frequency domains. |
