在人脸图像中确定嘴巴位置的方法

利用迭代式阈值选择算法在人脸的下半区域进行阈值化处理,无需人工干预就可得到嘴巴鼻子等区域,且很好地改进了传统的二值化方法所造成的嘴部轮廓不清晰、连通性不好等缺陷;用腐蚀膨胀算法去掉较小的噪声点,用最小外接矩形近似表示各个连通区域的形状,根据嘴巴形状大小的先验知识确定嘴巴所在的连通区域;用嘴巴连通区域的质心表示嘴巴中心,利用Harris角点检测算法在原灰度图像的嘴巴区域中找到两个嘴角。实验结果表明,本文算法具有较快的速度和较高的精度。

Application of numerical interval analysis to obtain self-validating results for multivariate probabilities in a massively parallel environment

Conventional computations use real numbers as input and produce real numbers as results without any indication of the accuracy. Interval analysis, instead, uses interval elements throughout the computation and produces intervals as output with the guarantee that the true results are contained in them. One major use for interval analysis in statistics is to get results of high-dimensional multivariate probabilities. With the efforts to decrease the length of the intervals that contain the theoretically true answers, we can obtain results to any arbitrary accuracy, which is demonstrated by multivariate normal and multivariate t integrations. This is an advantage over the approximation methods that are currently in use. Since interval analysis is more computationally intensive than traditional computing, a MasPar parallel computer is used in this research to improve performance.

WORK AND THE CITY IN THE e-SOCIETY A critical investigation of the sociospatially situated character of economic production in the digital content industries in the UK

The aim of this paper is to ground debates about the 'new economy' or 'e-society' in the practice of individuals and companies producing 'new media'. The uncontroversial starting point is to question the generalization in much theorizing, and the tendency to technological reductive accounts of social and economic change. The focus here is to point to the intellectual sources of much policy in this field. The authors present case study material of three very specific parts of the new media/digital content industries (film special effects, computer games and web design). The paper concludes that both technological reductive and agentic accounts have underplayed the continuing importance of the social and economic embeddedness of production, and of the situated co-constitution of technologies, people and places. The differences between industries associated with labour processes, labour markets, users and markets for goods are highlighted. These particularities begin to offer more robust accounts of location and organization.
