Algorithms for Visual Design
I found this book on Processing in Amazon.

Package themidibus //

The MidiBus provides a simple way to access and interact with installed MIDI system resources, although it's especially designed to be used with Processing, it could easily be adapted for use in any java program.

BlobDetection

This library is aimed at doing computer vision by finding ‘blobs’ on an image , that is to say areas whose brightness is above or below a particular value.

It allows to compute blobs’edges as well as blobs’bounding box. However, this library does not perform blob tracking, it only tries to find all blobs each frame it was fed with.

It was primarly developped for Processing (Beta) but can be used in any java programs.
