w2img::GMMFilter::GMM Class Reference

Inheritance diagram for w2img::GMMFilter::GMM:

w2img::GaussianMixtureModel::GaussianComponent List of all members.

Detailed Description

A Gaussian that holds, besides the probability of being at a particular place, what the sum of the values ought to be.

After the GMM fit, the total P() will sum to 1, so multiplying by the scale will allow the sum to be the same as the original blob that was fit.

Member Function Documentation

double w2img::GaussianMixtureModel::GaussianComponent::computeProbabilityDensityAt ( double  x,
double  y 
) const [inherited]

Value of Normal function at x,y given these parameters.

You typically want to weight this contribution by getWeight() This goes into the E-step in E-M.
