基于图像块复杂度和分段距离函数的人眼定位算法研究

针对有复杂背景的人脸中眼睛定位问题,本文采用肤色分割原理分离出背景信息,在人眼检测过程中采用寻找最大图像块复杂度的小块的方法,在人眼定位过程中采用计算分段距离函数的方法。本文精选了200张单人照片进行仿真实验,实验结果表明,上述解决方案可以从有干扰背景,人头侧向一方,甚至戴眼镜和帽子等饰物的图像中快速精确地识别出人脸和人眼。

Identifying development blocks—a new methodology

The paper specifies a quantitative methodology for exploring development blocks. The concept of ‘development block’ was a major contribution to the historical analysis of industrial transformation by the late Erik Dahmén, but development blocks have mainly been analyzed by qualitative methods and indirect indicators and not statistically identified. In this paper, development blocks are identified by means of a combination of co-integration analysis and Granger causality. Using these techniques, we are able to identify two partially overlapping development blocks in the Swedish economy, formed around the electricity generating sector: one with metal, metal goods, machinery and railways; and another with pulp and paper, chemicals, and machinery.

Estimating Water Demand under Increasing-Block Tariffs Using Aggregate Data and Proportions of Users per Block

The price specification suggested by Nordin (1976) for theanalysis of demand under block tariffs is applied to estimatewater demand functions using aggregate data from the Northwest ofSpain. The traditional way of using Nordin's specification whenonly aggregate data are available (using values of marginal priceand difference faced by the average user) is compared with thetheoretically correct one. The latter uses the average marginalprice and the average difference, these averages being weighted bythe proportion of users per block. The availability of data on theproportion of users per block permits also the explicit modellingof the choice of block. The results show that, in the sampleanalyzed, the values of price elasticity under the traditionalspecification and the more innovative one are not significantlydifferent.
