Idea – Open Source Small Project Collaboration?

I was thinking. Maybe there should exist a site where you can present and collaborate on small computing projects. I have lots of ideas that could be tested in a R/Scilab/Matlab environment. I’m sure others also have ideas that they need help to test.

An example of a small computing project I want to test.

Thinking about noise reduction. A start would be to look at a smaller scale of the photo. Usually that scaled down photo contains very little visible noise which is what I want. The objects I can see from that smaller image are the objects I want to keep. When zooming in I want to filter out those pixels that introduce new objects similar to the ones that we would call noise.
