Abstract
In this paper, we propose a top-down building reconstruction technique based on layover modelling and MCMC method. Through representing the layover with parameterized geometrical models, the problem is converted into an optimization problem under the Bayesian scheme. The energy function consists of two parts: region part and edge part. In order to obtain global optima, simulated annealing algorithm with MCMC is used in the optimization stage. Two groups of transmission kernels which are responsible for model updates are designed according to the model. This method is tested both on simulated SAR image and HR TanDEM-X data. At this moment, only qualitative analysis for this method is provided. It proves the effectiveness of the presented method. Detailed quantitative evaluation will be added when we submit the final version of this paper.
