Bundle Pooling for Polygonal Architecture Segmentation Problem

Figure 1 . Complex house structures can be parsed as a combination of simple primitives. Our system turns a photograph of a residential house (top left) into an assembly of simple polygonal primitives (top middle), while a standard detection system produces only axis-aligned bounding boxes (bottom middle). The polygonal representation enables applications such as photo-realistic virtual remodeling (bottom left), surface normal estimation (top right) or pop-up 3D billboards (bottom right).
