Ghosting Demo

This GUI implements the demo "Alpha Blending of Streamed Image Pairs" from the Image Acquisition Toolbox documentation. It is intended to show how to create a simple GUI that performs image processing as images are acquired by the Image Acquisition Toolbox.
This demo combines a background image with newly acquired images which a user specified transparency value. This produces a "ghosting" effect where objects that move into the scene appear to be partly transparent.
