Abstract:
1. A method, comprising: receiving, by a computing device comprising a processor, input image data, wherein the input image data represents a façade; reconstructing, by the computing device, the input image data comprising determining three-dimensional (3D) points, lines, and camera positions associated with the façade; performing, by the computing device, a multi-view semantic segmentation on the reconstructed input image data comprising: block partitioning, by the computing device, the reconstructed input image data into a plurality of independent object blocks comprising a first object block and at least a second object block, comprising ignoring vertical line segments comprising extensions that cross a defined number of horizontal line segments; and separating, by the computing device, the first object block from at least the second object block comprising using one or more line structures in the input image data, wherein the first object block and at least the second object block belong to a same object class.
