CVOCV was built in order to create an extremely simple and lightweight OpenCV experimentation environment for OS X 10.5.x. Using CoreVideo makes it possible to send video frames to OpenCV with a minimal amount of computational overhead.

In order to build this project, you must be running OS X 10.5 Leopard.

The XCode project can be downloaded here (Updated 1/24/09):

With only a single machine on which to run all of my applications, when I need to accomplish specific tasks, particular attention must be paid to performance. When I wrote this example, I was looking for a simple way to do OpenCV-based blob detection, but in a way that minimize CPU overhead. Existing approaches typically exist embedded within other infrastructures that make specific assumptions about the intent of the programmer. I needed a simple way to get blobs, and after finding them, to send the results to another application that is able to more appropriately handle its task.
