Second, the theory of scale space was used to design a new operator for target detection and tracking. Then, the property of scale invariant was analyzed and proved, and a tracking scheme based on the gradient LOG operator was proposed. Experimental results show that the gradient LOG operator is appropriate to describe small target in complex background, and the detection precision is in the level of sub-pixel. Furthermore, it is efficient and robust to noise.

The paper studies the distribution characteristics and determinants of job vacancies. The parameter estimation is based on the two-stage Tobit procedure. The main statistical results are as follows: There is a positive correlation between the hiring scale and job vacancy incidence, while there is a negative correlation between the qualification vacancy rate and the hiring scale. The higher the labor turnover rate in units, the higher the job vacancy incidences and the vacancy rates are. The 98.39% of institutions with prospects have labor needs, and 39.53% of units declining say they will hire new staff. After decomposing the Theil Index which reflects the gaps among vacancy rates, the differences among vacancy rates of different units are mainly from the inner causes of various groups, and the intergroup reasons are not main ones.

本文利用两阶段Tobit模型对国内的职位空缺统计数据进行了估计，发现：用人机构的雇佣规模与职位空缺发生率正相关，而职位空缺率则与机构的雇佣规模呈现负相关的关系；机构员工流动率越高，职位空缺发生率以及职位空缺率越高；在景气指数为"看涨"的机构中98.39%表示存在用人需求，而景气指数为"看跌"的机构里只有39.53%的机构表示会招募新员工；在对反映职位空缺率差距水平的泰尔指数分解后发现机构职位空缺率之间的不同主要是由于各类分组的组内原因导致的，而组间的原因并不是主要的。
