Referring to Hermann Hesse’s book “The Glass Bead Game” in which the glass bead game is closely related to music making we wanted to built a glass beat game in which a player or a group of players can make music by putting marbles on a game board. The idea includes building an instrument for simple music making as well as exploring the possibilities of using the setup as a game with rules focusing on topics like sound, music, spatialization, hearing, psychology, tactical behavior and synesthesia.

The project “Inter-Voice Morphing using a neural network based dimensionality reduction technique” is created in collaboration with Tommaso Villanova. In this project we have attempted to set up the first experiments for a novel way to generate and morph voice sounds. In this project we use a special case of a feedforward neural network and train it using a large phoneme dataset. The idea is to encode the phoneme data in the neural network and extract its minimal amount of principal components. After training the neural network is used to construct a synthesizer for voice (phoneme) sounds.

Finished this project about a month ago. Its about retrieving scenes (scenic pictures) from a database using visual information retrieval techniques only. You can just give the program an image you found or took and then the program will try to find similar pictures. The retrieval part uses a variety of techniques and concepts like the perceptually uniform CIE L*A*B* colour space, the Self Organizing Map (Kohonen Neural Networks) and Sobel Edge detection.
