In this paper, my aim is to add to the discussions of sorcery in Melanesia by focussing on its relation to economic agency in the context of a case example from Malaita, Solomon Islands. Using Taylor's (2015) categories of ‘distributive’ and ‘possessive’ agency as a critical point of departure, I illustrate how sorcery can be considered as an outcome when people are perceived not to be balancing these...
This work describes an unsupervised method to extract 2D and 3D inner earth structures from seismic reflection measurements m order to support an expert, interpreting the data. The problem is solved with a general texture segmentation approach, which first extracts characteristic patterns for seismic events (feature extraction stage, described in Section 2) and then groups data elements with similar...
Intelligent surveillance has become an important research issue due to the high cost and low efficiency of human supervisors, and machine intelligence is required to provide a solution for automated event detection. In this paper we describe a real-time system that has been used for detecting tailgating, an example of complex interactions and activities within a vehicle parking scenario, using an...
This paper presents an unsupervised segmentation method applicable to both 2D and 3D images. The segmentation is achieved by a bottom-up hierarchical analysis to progressively agglomerate pixels/voxels in the image into non-overlapped homogeneous regions characterised by a linear signal model. A hierarchy of adjacency graphs is used to describe agglomeration results from the hierarchical analysis,...
