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.
中文摘要:本课题是在合作首次发展了氧化物薄膜原子尺度层状外延生长光学原位实时探测方法的基础上立项的,三年来,我们充分发挥双方的优势和特点,圆满完成了课题的设想和计划。1、在物理所建立了一套先进的光反射差法装置,编写了计算机系统的数据采集程序,实现了两路光学信号和RHEED数据的同步采集和显示。2、用激光分子束外延在SrTiO3基底上生长SrNb0.1Ti0.9O3薄膜,首次观测到连续外延几百个原胞层,周期振荡的光反射差实部和虚部信号,证明了光反射差法是一种能原位实时探测与监控薄膜层状外延生长的好方法。3、首次验证了通过对生长表面原子或分子台阶密度的响应,光反射差法可用于原位实时监测在连续生长条件下薄膜的层式生长模式。4、通过唯象理论的研究,证明光反射差信号由三项组成,第一项只与薄膜的平均厚度和宏观光学电介质常数有关;第二项与分子台阶面覆盖度和台阶面上分子层的光学电介质常数有关;第三项与台阶边缘的覆盖度成正比,并和在台阶边缘的分子的有效光学介电常数有关。

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. The experimental results on Windows platform indicate the modest CPU and memory consumption, so as to meet the requirement of real time applications.

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.
