Shape model fitting using MCMC
In this week we will learn how to formulate Shape model fitting problems as a Bayesian model and will see how we can implement this in Scalismo.
We start with the simplest case, where the pose is fixed and corresponding landmarks are used. By including additional parameters, such as translation and rotation parameters and at the same time relaxing assumptions regarding correspondence, we make the model useful for a wide variety of shape analysis tasks. Finally, we also show how we can formulate a likelihood function based on ideas from Active Shape Model fitting. We thus arrive at a practical method to fit a model to an image.
