基于样块改进的图像修复算法

图像修复是指对图像破损区域进行填充或者将图像中多余物体进行移除。在Criminisi算法的基础上进行改进,在待修复块优先权的计算过程中,由于等照度线的曲率可以反映图像的局部特征,块与块之间的方差值可以反映图像的边缘信息,因此,将二者考虑进来,确保修复过程能够准确有序地进行。在寻找最佳匹配块时,将等照度线的曲率也作为一个因素增加进来,有效地提高了最佳匹配块搜索的精确性。经过仿真实验证明,改进后的算法不仅在PSNR值上比原算法有所提高,而且修复结果也比原算法更加准确可靠。     

基于战例数据的制胜要素选择方法

针对战争制胜机理定量研究需求,提出了一种基于混合评估的制胜要素选择算法。针对战例数据特点,该算法选择两种过滤方法分别从不同方面对要素全集进行评估排序而后加权得到综合排序结果;将结果作为遗传算法的初始种群,而后以分类精度作为个体适应度函数。选择几种典型的分类器综合比较,筛选出规模较小、性能较好的要素子集。测试结果表明,该算法不仅能有效地减少要素子集规模,还可以进一步提高制胜机理分析模型的准确率和效率。

Responsibility in Complex Conflicts: An Afghan Case

This paper discusses soldiers’ moral responsibility in today’s complex conflicts. The point of departure is the increased focus on soldiers as moral decision-makers in war, illustrated by the introduction of core values in the Norwegian Armed Forces. Responsibility is one of these core values, but it is not clear exactly how we should understand responsibility. I use a case where a group of Norwegian soldiers in the International Security Assistance Force (ISAF) sought the cooperation of a group of mujahedeen to solve the military mission of establishing security. As confidence between the parties grew, the soldiers became horrified witnesses to a practice of bacha bazi, where a young boy is dressed up for entertainment and sexual abuse. This situation gives reason to question the limits of role responsibility, the status of soldiers’ legitimacy, and the challenges of making morally sound judgments in a multicultural context. The discussion demonstrates that, even if there are restrictions on the soldiers’ freedom to act, a responsibility reaching beyond or extending their role should be recognized as part of the moral reality of modern soldiers.     

From Nationalism to Factionalism: Faultlines in the Naga Insurgency

Do ceasefires or peace talks create fragmentation in the insurgent groups? Rather than proposing claims that can offer predictions about armed groups behaviour under ceasefires or peace processes, the analysts tend to focus largely on the dynamics between state and non-state actor. The experts pay little attention to overtime changes in social and local political context which might contribute to propelling a rebel group towards fragmentation and factionalism. The present study intends to fill this gap by exploring the shifting role of public opinion and ethnic support for the peace talks to ascertain whether it can increase the likelihood of factionalism in rebel groups or not. This article applies this approach to the case of Naga National Movement (1947–2015) in India, and finds that the proposed variable appears to have increased the frequency of factionalism in the movement.     

Civilian protection in Africa: How the protection of civilians is being militarized by African policymakers and diplomats

This article explores how the protection of civilians is being militarized by African policymakers and diplomats. I draw on practice approaches to analyze what social groups are doing when they claim to “protect civilians.” I show how innovative protection mechanisms can be seen as a function of officials and diplomats coping with the changing circumstances of increasingly militarized politics in Africa. Specifically, accountability mechanisms for unintended and intended civilian harm by African security operations have originated in connection with this development. I argue that these are results of anchoring practices, which means that everyday informal interactions in one context become linked to another context. I argue that these emerging accountability mechanisms represent a new combination of practices, with the potential of changing the routine activities and mutual learning between policymakers and diplomats.     

The human consequences of foreign military intervention

The empirical international conflict literature has given much recent attention to interstate armed force’s impact on human well-being. While empirical research has advanced our understanding of the phenomenon considerably, we argue that one conclusion that many studies have reached is preliminary. Some recent research contends that only full-scale war, and not force short of war, has a discernable impact on human welfare or physical quality of life (PQOL). We develop theory on one type of force short of war, large-scale foreign military intervention (FMI), and its potential effects on PQOL. Using interrupted time series and panel corrected standard error methodologies, we find that from 1960 to 2005 large-scale FMI had a statistically and substantively significant impact on the PQOL of populations in 106 developing countries. The specific effect that this type of armed force has depended in large part on the regime type of the target country.
