Towards a conceptual model and reasoning structure for insider threat detection (2013)
Journal Article

The insider threat faced by corporations and governments today is a real and significant problem, and one that has become increasingly difficult to combat as the years have progressed. From a technology standpoint, traditional protective measures suc... Read More about Towards a conceptual model and reasoning structure for insider threat detection.

Transformation of an uncertain video search pipeline to a sketch-based visual analytics loop (2013)
Journal Article

Traditional sketch-based image or video search systems rely on machine learning concepts as their core technology. However, in many applications, machine learning alone is impractical since videos may not be semantically annotated sufficiently, there...

Improving accuracy and efficiency of mutual information for multi-modal retinal image registration using adaptive probability density estimation (2013)
Journal Article

Mutual information (MI) is a popular similarity measure for performing image registration between different modalities. MI makes a statistical comparison between two images by computing the entropy from the probability distribution of the data. There...

Glyph sorting: Interactive visualization for multi-dimensional data (2013)
Journal Article

Copyright © 2013 The Author(s). Glyph-based visualization is an effective tool for depicting multivariate information. Since sorting is one of the most common analytical tasks performed on individual attributes of a multi-dimensional dataset, this mo...
