Texture Prior EvaluationOverviewParametersFormal ProblemFormulationPrior EvaluationLikelihoodEvaluationWall Plane PriorEvaluationShape PriorEvaluationTexture PriorEvaluation⊲rjMCMCModel AcquisitionAlgorithmThe texture prior, P(θ T |θ L θ P θ G MI), is learnt <strong>from</strong> a settraining <strong>of</strong> images. To reduce the impacts such as lightning<strong>and</strong> scale <strong>of</strong> the textures, a wavelet decomposition is appliedto the images. The output <strong>of</strong> that decomposition gives 4transformed images: HH, HL, LL <strong>and</strong> HH, where the firstletter st<strong>and</strong>s for the horizontal direction <strong>and</strong> the second forthe vertical direction; H indicates the high-pass <strong>and</strong> L thelow-pass filter, respectively. These outputs are quantised <strong>and</strong>put into bins.Results18 / 35
