Simultaneous use of measured results from audio-visual ("μετροφωνία", asymmetrical interval sequences, "διπλοπαραλλαγή") and somatokinetic ("χειρονομία", "foot-hand-voice" lever effect, "ἄλογος χρόνος", golden section and iterative subdivisions thereof, as wel...

Today’s technology allows for [a] sampling and digital representation of a number of parameters that can be extracted from either audio files (Sonic Visualizer®, Melodos®) or from printed as well as manuscript material (Gamera psaltiki OCR ) in either Contemporary or Paleographic Psaltic Notation as it can be found in various languages, [b] statistical analysis as well as distribution/classification of this information within some database, which can furthermore be [c] searched using homologous formular sequences (by applying methods analogous to those used in molecular biology) so as to exploit all this ...

Simultaneous use of measured results from audio-visual ("μετροφωνία", asymmetrical interval sequences, "διπλοπαραλλαγή") and somatokinetic ("cheironomia", "foot-hand-voice" lever effect, "ἄλογος χρόνος" and "καταλλαγὴ χρόνου") components is a key to memorisation, transmission as well as traditional performance of Psaltic and Gregorian chant, both of which are complementary aspects of a common formular database, differentiated by "rhythmic emphasis" and "polar note" variations, which provide for quite asymmetrical rhythm in "ecphonetic", and lesser so in "papadic" formular contraction/expansion renderings, respectively.

We propose algorithms for page segmentation, lyrics removal, syntactical symbol grouping and the determination of characteristic page dimensions. All algorithms are experimentally evaluated on a variety of printed books for which we also give an optimal feature set for a nearest neighbour classifier. The system is based on the Gamera framework for document image analysis. Given that we cover all aspects of the recognition process, the paper can also serve as an illustration how a recognition system for a non standard document type can be designed from scratch.
