track-to-track moving
3.The linear regression equation of mandibular incisal point move distance on arrowy axis along with the occlusal interference position was:■=4.9429+0.1336x1,δ=0.3144,P<0.001.CONCLUSION:The position of occlusal interference affected the track of mandibular incisal point during protrusive movement significantly,such as that along with the retrusion of the occlusal interference,the mandible protrusive moving track tended to be more anterior and partially to the contralateral side.
4.This paper presents an algorithm of moving region detection based on chroma, which is able to cope with varying illumination and shadow problems, and refines the detection results with morphology, by marking each moving region in the binary image, the geometrical features parameters such as area, perimeter and form factor can be extracted, which lay the foundation for the analysis and track of moving target.
5.The characteristics are as follows: American male projects and Russian female projects dominate, respectively; the centre of world track and field sports is moving from Europe to America, but European countries have their own special projects; African track and field strength enhances, and its moderate and long distance running projects become dots of lights; a fn Asian projects act in opposition with European, American or African ones Oceanian strength still does not see improvement.
9.The change regulation of sample interval in sector scan TWS radar is discussed. Based on the interval change regulation resulting from the antenna is moving to and fro, the interval filtering and prediction equation for tracking target and track managing, system in sector scan TWS radar are developed, α β filtering and predicting formula in polar coordinates for sector scan radar is established.
