2019 arXiv   pre-print
In this paper, we present a methodology that uses such computer vision techniques to automatically compare the efficiency of several visualization techniques.  ...  To show that our methodology can reproduce, up to a certain level, results of user evaluations, we applied it to compare two mainstream graph visualization techniques: node-link (NL) and adjacency-matrix  ...  Our methodology has been applied on the comparison of two well-known graph visualization techniques: AM and NL diagrams.  ...

The problem of face recognition is discussed. The main methods of recognition are considered.  ...  As a result, a 3D mask of the face is obtained. Using three anthropomorphic points, then constructed a coordinate system that ensures a possibility of superposition of the tested mask.  ...  Elastic graph matching The essence of the method is reduced to elastic comparison of graphs describing images of faces [24] . Faces are represented as graphs with weighted vertices and edges.  ...

Relaxed selection techniques for querying time-series graphs

Christian Holz, Steven Feiner
2009 Proceedings of the 22nd annual ACM symposium on User interface software and technology - UIST '09  
Time-series graphs are often used to visualize phenomena that change over time.  ...  However, tools that support time-series graphs typically separate query specification from the actual search process, allowing users to adapt the level of similarity only after specifying the pattern.  ...  If a user made 15 repeated adjustments to their query, the application would move on to the next dataset (automatic transition).  ...
