scalismo.faces.sampling.face.evaluators
variance of squared differences, in relative units of sigma^4
expected standard deviation between image and target pixels (noise assumption, total RMS distance), sigma2 = E[d2]
(Since version ) see corresponding Javadoc for more information.
Collective Likelihood: models the average squared distance of images as normal (valid for many pixels, large averages: Central Limit Theorem) for Details see "Markov Chain Monte Carlo for Automated Face Image Analysis" in IJCV 2016
