Are there any open source biomedical signal processing projects? I'm in a biomedical engineering master's program and am mostly interested in signal processing. Unfortunately, I feel that I'd like to get deeper into the subject, and my university can't accommodate that request -- there's a limited number of courses, and the professor I've asked doesn't know of any local project that I could join.

Are there any open source projects related to biomedical/bioelectric signal processing?

If not, could you recommend any other type of beneficial extracurricular activities? I could probably spend 1-2h a day on this project.
For image processing in biology, there is the FIJI project, a very worthwhile endeavor. They have a list of project ideas as well, maybe there's something that's perfect for you?
