OtsuWeighted
public class OtsuWeighted extends CalculateLevel
Similar to Otsu, but weighs the variances differently of background and foreground.

The standard otsu method seeks both foreground and background to have similar variance. But many for real world cases (e.g. fluorescent microscopy) one expects the background to be have much less variance, as it is very low-valued.

This algorithm allows the foreground and background variance to be non-equally weighted to a priori account for low-variance backgrounds.
