In structural pattern recognition, a major drawback of graph based representation is the lack of algorithmic tools. To overcome this lack, we embed graphs in vector spaces by means of prototype selection and graph edit distance, thus making them available to all algorithms of statistical pattern recognition that operate on feature vectors. In previous work a similar procedure was applied. However,...
Graphs are powerful data structures that have many attractive properties for object representation. However, some basic operations are difficult to define and implement, for instance, how to obtain a representative of a set of graphs. The median graph has been defined for that purpose, but existing algorithms are computationally complex and have a very limited applicability. In this paper we propose...
The aim of writer identification is determining the writer of a piece of handwriting from a set of writers. In this paper we present a system for writer identification in old handwritten music scores. Even though an important amount of compositions contains handwritten text in the music scores, the aim of our work is to use only music notation to determine the author. The steps of the system proposed...
