基于局部色调映射的异源图像匹配方法

色调映射是一种适用于亮度和对比度变化的快速图像匹配方法。由于异源图像间存在复杂的灰度变换关系,直接采用色调映射方法进行匹配的成功率通常难以满足应用需求。为了提高匹配成功率,本文提出基于局部色调映射的异源图像匹配方法。首先将实时图划分为不重叠的子区,对每个子区进行直方图均衡化和弱切片变换,通过局部色调映射计算子区与基准图的距离系数图。融合全部距离系数图得到图像匹配结果。实验结果表明,该方法匹配成功率高于现有的色调映射方法,且计算时间仅略高于现有方法,优于异源图像匹配中常用的互信息方法。

The effects of local elections on national military spending: A cross-country study

In this paper, we study the domestic political determinants of military spending. Our conceptual framework suggests that power distribution over local and central governments influences the government provision of national public goods, in our context, military expenditure. Drawing on a large cross-country panel, we demonstrate that having local elections will decrease a country’s military expenditure markedly, controlling for other political and economic variables. According to our preferred estimates, a country’s military expenditure is on average 20% lower if its state government officials are locally elected, which is consistent with our theoretical prediction.     

Close Encounters of the Tribal Kind: the Implementation of Co-option as a Tool for De-escalation of Conflict – The Case of the Netherlands in Afghanistan's Uruzgan Province

Abstract

In contemporary counter-insurgency campaigns de-escalation is typically achieved by obtaining the local population's collaboration. The rationale underlying this approach is that such collaboration spawns control over the population and therefore weakens the insurgent's position. This article seeks to understand how this approach is practised in the reality of contemporary counter-insurgency warfare. In Iraq as well as Afghanistan counter-insurgents were confronted with fragmented indigenous societies in which the various local segments were dominated by local power-holders. Consequently, obtaining the local population's collaboration required co-option of these agents. As such a strategy of co-option is a highly localized approach, this article focuses on Afghanistan's Uruzgan province and analyzes the implementation of co-option by the Netherlands' Task Force Uruzgan (TFU), which operated there from 2006 to 2010. The analysis discusses how the counter-insurgents obtained a profound understanding of Uruzgan's societal landscape and how co-option of local power-holders became part of the counter-insurgency routine. In the end, co-option was successfully implemented as TFU even succeeded in obtaining the collaboration of previously marginalized elements of the population. However, as the methods employed for co-option were mainly of a persuasive nature, the TFU co-option strategy was less effective in containing the influence of notorious spoilers. Thus this case study provides an insight into the dynamics and limitations of co-option as a tool for de-escalation in contemporary counter-insurgency warfare.
