Simple camera processing

This is a C implementation of a demo visual processing preceptual component. As such, it expects a USB camera connected to the computer. It provides elementary fucntionality, as it calculates the average frame intensity and the frame-by-frame difference. It then populates the metadata feed. It serves as an example on how to interface the camera and how to populate feeds within C. It requires two external libraries:

• OpenCV for interfacing the camera and processing the incomming images, and
• cURL for communicating with the edge node. For extensive information on the contents of the subirectories of the project, refer to the Readme.txt file located in its root folder.
