Quantity of motion of an arbitrary number of inputs

In video analysis I have been working with what is often referred to as “quantity of motion” (which should not be confused with momentum, the product of mass and velocity p=mv), i.e. the sum of all active pixels in a motion image. In this sense, QoM is 0 if there is no motion, and has [...]

Black box in the lab

Last week we started setting up a “black box” in the new lab space. It is great to finally have a more permanent motion lab set up that we can use for various types of observation studies and recording sessions.

Janer’s dissertation

I had a quick read of Jordi Janer’s dissertation today: Singing-Driven Interfaces for Sound Synthesizers. The dissertation presents a good overview of various types of voice analysis techniques, and suggestions for various ways of using the voice as a controller for synthesis. I am particularly interested in his suggestion of a GDIF namespace for structuring [...]

Kickoff-seminar

Some pictures from the kickoff-seminar for the Sensing Music-related Actions project last week: Project leader Rolf-Inge Godøy started with a short presentation of the new project. Then Marcelo M. Wanderley (McGill, Montreal) held an overview of various types of motion capture solutions, and the pros and cons of each of them. He stressed two main [...]

Optitrack motion capture

I held a guest lecture at the speech, music and hearing group at KTH in Stockholm a couple of weeks ago, and got a tour of the lab afterwards. There I got a demonstration of the Optitrack optical motion capture system, which, as compared to other similar systems, is an amazingly cheap solution starting at [...]
