Hierarchical Space Tiling for Scene Modeling

  title={Hierarchical Space Tiling for Scene Modeling},
  author={Shuo Wang and Yizhou Wang and Song-Chun Zhu},
Three types of HST: square tiling (e.g., Quadtree and Spatial Pyramid), rectangular tiling (HST-RECT), triangular tiling (HST-TRI) Representation Given a set of scene configurations (scene label maps), we present a learning-by-parsing (EM-like) method to learn the HST representation including the branching probability at Or-nodes and the tiling dictionary. E-Step: fix HST and infer parse tree by dynamic programming M-Step: based on the inferred parse trees, estimate HST by Maximum Likelihood… CONTINUE READING
