In many computer vision tasks  in order to improve the accuracy and robustness to the noise  wavelet analysis is preferred for the natural multi-resolution property. However  the wavelet representation suffers from the dependency of the starting point of the sampled contour. For overcoming the problem that the wavelet representation depends on the starting point of the sampled contour  the Zernike moments are introduced  and a novel Starting-Point-lndependent wavelet coefficient shape matching algorithm is presented. The proposed matching algorithm firstly gains the object contours  and give the translation and scale invariant object shape representation. The object shape representation is converted to the dyadic wavelet representation by the wavelet transform. And then calculate the Zernike moments of wavelet representation in different scales. With respect to property of rotation invariant of Zernike moments  consider the Zernike moments as the feature vector to calculate the dissimilarity between the object and template image  which overcoming the problem of dependency of starting point. The experimental results have proved the proposed algorithm to be efficient  precise  and robust.

In order to match the intersectant targets' tab when these objects separate  a kind of method that makes use of fuzzy multi-parameter to match targets is proposed. Multi-parameters include the forecasted position after targets separate  target speed  target size and geometry shape  and different parameter corresponds to different influence coefficient  evaluate the integrated matching coefficient that every observation target corresponds to forecasted target  and the corresponding relationship that matching coefficient is the biggest is the best matching result. In order to locate the position and speed of forecasted target  a new method of track forecast is proposed  firstly  Hough transform is used to the object's track before objects intersect  by this  the object's positions that the warp between forecasted location and observation location is large enough is eliminated  then least square method is used for track forecast by the remainder valid positions  and get hold of the forecasted position when objects separate. The experiment results show: when tracking the bulky objects which intersect and separate  the right identification probability of traditional least square method is 87.5%  and the right identification probability of fuzzy match by multi-parameters can attain 96%  the reliability improves in evidence.
