From the viewpoint of vector correlation in high dimensional space,the difference of two images was analyzed It uses vector to present the image information and calculates the angle of two vectors as the metric of correlation of face candidate and mean face template.

To improve the speed of image matching,an algorithm based on searching strategy along the border and vector correlation are presented.

The vector correlations between products and reagents for the reaction Ca+CH3I→CaI+CH3 are studied using quasiclassical trajectory(QCT)method on extended London-Eyring-Polanyi-Sato potential energy surface(PES)at different collision energies.

The vector correlation study of the reactions of chlorine atoms with methane and perdeuterated methane;

The vector correlations between products and reagents for the N(2D) + H2 → NH + H reaction have been calculated by the quasi-classical trajectory(QCT) method on an accurate potential energy surface(PES) of Ho et al.

The vector correlations between products and reagents for exothermic reaction F+HI→HF+I are studied using quasi-classical trajectory(QCT) method at three collision energies of 0.
