Stereo Correspondence Through Feature Grouping and Maximal Cliques
In this paper we propose a method to solve the stereo correspondence problem. The method matches features and feature relationships and can be paraphrased as follows. Linear edge segments are extracted from both the left and right images. Each such segment is characterized by its position and orientation in the image as well as its relationships with the nearby segments. A relational graph is t...
متن کاملNonmetric Multidimensional Scaling
Although the assignment was to write a note about the famous, highly cited Kruskal 1964 papers, it would hardly be fair if the topic wasn’t described in the context of two other papers, being Shepard’s 1962 papers (with 2309 citations in Google Scholar as of 4/1/2016) that started the development of what is called nonmetric multidimensional scaling. Before getting into more detail, some of the ...
متن کاملRepresentative Selection in Nonmetric Datasets
This paper considers the problem of representative selection: choosing a subset of data points from a dataset that best represents its overall set of elements. This subset needs to inherently reflect the type of information contained in the entire set, while minimizing redundancy. For such purposes, clustering may seem like a natural approach. However, existing clustering methods are not ideall...
متن کاملOn Degenerate Nonmetric Unfolding Solutions
Loss functions proposed for nonmetric unfolding are discussed critically. Practical experience suggests that they do not work, mathematical reasons are sought why this is. Although the loss functions are constructed in such a way that they are ill-behaved at trivial solutions, it is shown that they are rather well-behaved along differentiable paths to trivial solutions. It is shown that in the ...
متن کاملInternet Attack Knowledge Discovery via Clusters and Cliques of Attack Traces
There is an increasing awareness of the growing influence of organized entities involved in today’s Internet attacks. However, there is no easy way to discriminate between the observed malicious activities of script kiddies and professional organizations, for example. For more than two years, the Leurré.com project has collected data on a worldwide scale amenable to such analysis. Previous publ...
