Claim One:
1. A method that facilitates image-based façade modeling, comprising: determining, by a system comprising a processor, a composite texture image associated with a sequence of captured images, including obtaining camera positions associated with the sequence of captured images and obtaining three dimensional (3D) points associated with the sequence of captured images used to determine the composite texture image; decomposing, by the system, a data representation of a façade that is based at least in part on the composite texture image, the camera positions, and the 3D points, by recursively subdividing the data representation of the façade into a set of subdivided patches; bottom-up merging of at least a subset of the set of subdivided patches by merging neighboring subdivided patches based at least in part on a determination that a measure of support to separate neighboring subdivided patches based on architectural bilateral symmetry is not enough; structuring, after the bottom-up merging, the data representation of the façade into a directed acyclic graph of rectilinear patches; and augmenting the data representation of the façade with depth information based on the sequence of captured images and a subset of the 3D points by determining, by the system, and assigning an optimized depth to at least one of the subdivided patches.
