A frame image of a video frequency sequence is read into a postpositional memory zone, and staring position and size information of a tracked object is obtained in the frame, then distribution statistical information of a target signature is extracted to build a gauss mixed model as an object template, a mean vector and a covariance matrix in gauss mixed distribution are used to describe the position and the size of the object, then the next frame image of the video frequency sequence is read into the postpositional memory zone. In a new frame video frequency image, a parameter estimation method is used to obtain object gauss mized model parameters in the current frame in iterative computation and find candidate template similar to the object template, and the final model parameters obtained in iteration are used to update the tracking window for realizing self-adaption of the tracked window.

The application results from fluorination showed microwave heating could accelerate chemical reactions markedly. The reaction time could be shortened 50% at least than that of conventional heating. The relationship between fluorinating agents\' structure and their activity was studied systematically. In addition, an anhydrous KF with higher activity was prepared by using expansion effect of microwave heating. As we known, solvents were very important to reaction. The comprehensive study showed some less polar aromatic solvents could be used as dipolar solvents. In addition, they had better effect than dipolar solvents in some occasions, such as fluorination of chlorobenzaldehydes and chlorinated diphenyl ketones etc. The primary applications of ionic liquids were also studied which indicated reactions with ionic liquids as solvents were more efficient and simple.
