Shape Prior EvaluationOverviewParametersFormal ProblemFormulationPrior EvaluationLikelihoodEvaluationWall Plane PriorEvaluation⊲Shape PriorEvaluationTexture PriorEvaluationrjMCMCModel AcquisitionAlgorithmResultsThe architectural shape prior for primitives,P(θ S |θ L θ P θ G MI), is defined <strong>and</strong> assessed using a MarkovChain simulation. This prior encodes information about:□□□□The scale <strong>of</strong> each primitive (if absolute scale is known).The shape <strong>of</strong> each primitive.The alignment <strong>of</strong> primitives.Other spatial relations, such as symmetry about avertical axis.As it is not feasible to draw samples <strong>from</strong> this distributiondirectly MCMC has to be used. They use Reversible JumpMarkov Chain Monte Carlo sampling, because <strong>of</strong> the varyingdimension <strong>of</strong> the parameter space.17 / 35
