Models image as sample from one of 2 Gaussians in RGB space. Classifies each pixel as having originated from one Gaussian.

In the future this could be expanded to remove the ith, kth, etc Gaussians from an N-Gaussian image model.

RemoveBackground.m contains a demonstration of how to use the main function, separate.m
