Abstract

In this paper, we propose a method for obtaining a textured billboards representation of a static scene, given a sequence of calibrated video images. Each billboard is a textured and partially transparent plane into which the input images are mapped using perspective projection. Binning using Hough transform is used to find the position of the billboards, and optic flow measures are used to determine their textures. Since these billboards are correct only from specific view-points, view-dependent rendering is used to choose and display appropriate billboards to reproduce the input.
