CASSANDRA

CASSANDRA was the NWO project on which my PhD was based. CASSANDRA stands for Context-Aware SenSing for AggressioN Detection and Risk Assessment. Goal was to detect human activity, specially aggression, in dynamic environments. Because a single sensormodality cannot always detect this audio and video analysis was performed. The two were combined in order to arrive at a cognitive description of the environment. Currently we are wrapping up by writing a joint journal paper with our partners at the university of Amsterdam.

Phoneme recognition

Together with Bea Valkenier we are researching how my work on sound source extraction can be applied to recognize vowels and consonants. We have succesfully recognized vowels and are now broadening our view to consonants.

Software implementation

The methods developed during my PhD and some more basic signal processing methods are implemented and optimizes in C. This will result in faster, more efficient code that can run independent of Matlab. The implementation in done by DySi and financed by INCAS3

Annotation

An important problem in sound source recognition is the lack of extensive, well-annotated datasets. In April of 2009 we started daresounds.org, a to-be-collection of these datasets. Also we are building tools to facilitate the annotation of recordings.
