基于联合相似测度的SAR图像边缘点特征配准方法

针对SAR图像配准过程中几何变换影响特征匹配稳健性和适应性的问题,提出了一种在特征匹配过程中直接解算几何变换模型的边缘点特征配准方法。利用SAR图像边缘点的梯度和方向特征,基于像素迁移思想,定义了图像匹配的联合相似度——联合特征均方和(SSJF),并建立了SAR图像边缘点集相似性匹配准则;基于方向模板提出了改进的ROEWA算子;利用改进的遗传算法(GA)来进行相似度的全局优化搜索,获取配准模型参数;利用多幅SAR图像的配准试验,对本文方法的性能进行了验证。     

Colonial violence and its ‘Small Wars’: fighting the Kuki ‘guerillas’ during the Great War in Northeast India, 1917–1919

ABSTRACT

This paper concerns the lesser known British counterinsurgency (COIN) operations in Northeast frontier of India during the First World War. Officially known as the ‘Kuki Operations’, it was considered as part of the Great War. Carried out in isolation from press and public, and shelved in colonial archives, the event remained invisible until today. Yet, it registers a critical case of colonial COIN doctrine where the ‘moral effect’ doctrine was employed without being questioned. It unleashed enormous amount of organized violence, ranging from shoot at sight to indiscriminate burning of villages, wholesale destruction of property and livestock, prevention of cultivation and rebuilding of villages, forced mass displacement in jungles or in ‘concentration camps’, and collective punishment (communal penal labour and payment of compensation) after the war. This paper argues that the theory of ‘minimum force’ and the practicability of the ‘moral effect’ doctrine as applied by the Empire, sit oddly with each other at the frontier, where violence was seen both as a natural and moral orders. Violence as an ‘imperatively necessary’ method to bring order in a disorderly frontier, in the opinion of colonial state, informs and registers Northeast India as geography of violence.

One size does not fit all: personalized incentives in military compensation

A critical element in implementing a compensation scheme including nonmonetary incentives (NMIs) is recognizing that preferences vary widely across Service members. There are at least three sources of variability: across different population classes, across individuals within a population class, and across NMI packages for a particular individual. Surveys across different military communities, ranks, and years of Service show the difficulty of identifying any NMI that has significant value for even 50% of the active duty force. At the same time, approximately 80% of the surveyed Service members expressed a significant positive value for at least one NMI. Therefore, one-size-fits-all incentive packages will not be nearly as effective as more personalized incentive packages. The authors discuss variability in Service member NMI preferences and outline an approach to implementing personalized NMI packages in military compensation through a sealed-bid reverse auction, where Service members select individual NMIs from a “cafeteria-style” menu of options.
