In order to deal with the template drift problem of MCD,MFD adjusts the pixel close threshold dynamically,and uses another correlation method to filter from multiple matching points that may be exist.

Realizing robust and accurate visual object tracking is challenging, because 1) the target appearance keeps changing; 2) template drift frequently occurs in which the template is gradually occupied by the background; 3) the target is often occluded during trackin.

We propose an algorithm addressing the problem of template drift in object tracking.

Phanerozoic apparent polar-wander paths of Tarim and plate motion;

In the application of ART-2 neural network, it is found that there is a characteristic of “pattern drifting” when processing the single-direction gradually changing patterns.

Lack of pattern drifting also exists and the causes for this lack were analyzed.

Final-ly,the problem of"pattern drifting"is successfully resolved by applying the refinement algorithm to the ART-2.

Drift Model for Ship out of Control at Sea;

Precisely determining the drift model coefficients is the key to successful long-time operation with the na- vigation systems.

It points out that the chose of distribution parameter C o and drift velocity V vj may have significant effect on the result of static and dynamic analysis of the system, when one dimensional two phase flow drift model with conservation equations for mass, steam, energy and momentum was used.
