查询词典 time scale

In order to resolve the conflict between excessive data storage, time expensive computation and real-time image processing, a method is proposed based on distance transfer with chamfer to extract the position and scale features of each objects, then a five points square predictor is used to estimate the position of objects next time and compute the velocity. Finally, objects are associated using improved weighed nearest neighbor. The algorithm is implemented on the platform of Xilinx XCV300E+ADI Blackfin 532 DSP.

为了解决多目标跟踪中数据存储量、运算量大与实时处理之间的矛盾，提出了一种基于倒角算子距离变换的多目标分离方法，分别提取出各个目标的位置和大小信息，再采用五点二次预测估计出下一场目标的位置从而得到目标的运动速度，最后由改进的加权最近邻算法进行目标特征关联。

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.

A better algorithm and corresponding real time implementation scheme are proposed. By methodic arranging the clocks of CPU and AD/DA, the scheme can not only scale the pitch in two octave range effectively, but also process the real time input audio for synchronous scaling output.

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.

Their proportions are 4:4:4:4:3. Then choose the healthy mice. Firstly, to set up the reflex of escaping lightening stroke by trained mouse; secondly, to make it vertiginous by rotation. The consciousness response period is the measuring time which every mouse needs from vertigo to consciousness comeback; and the freedom movement response period is the measuring time which every mouse needs from vertigo to freedom movement comeback. We used CRP and FMRP to scale the extent of vertigo. At the same time, we inspected the mice's appetite and psychosis. Above all, we observed the effect of this prescription in preventing and curing kinetosis. Besides, we contrasted this prescription with Dimenhydrinate and Scopolamine.
