The aim of this code is, given a still image as a RenderedImage, to compute a predicted popularity (0--100%) and a condfidence (0.0--0.1).
The aim is to be reasonably accurate yet use little memory or CPU.
The predictor code is shipped as a "safe" Java class that can run in a very limited sandbox (eg for an Applet of JWS) and that is guaranteed to run in finite time and with limited resources. This class complies with a simple standard interface, and thus can be plugged back into the live server or run in the the user's browser or (for example) the JWS upload tool.
This system can be calibrated/trained against the live vote database.
