Item Open Access Piecewise-planar 3D reconstruction in rate-distortion sense(IEEE, 2007-05) İmre, E.; Güdükbay, Uğur; Alatan, A. A.In this paper, a novel rate-distortion optimization inspired 3D piecewise-planar reconstruction algorithm is proposed. The algorithm refines a coarse 3D triangular mesh, by inserting vertices in a way to minimize the intensity difference between an image and its prediction. The preliminary experiments on synthetic and real data indicate the validity of the proposed approach.Item Open Access Rate-distortion based piecewise planar 3D scene geometry representation(IEEE, 2006) Imre, E.; Alatan, A.A.; Güdükbay, UğurThis paper proposes a novel 3D piecewise planar reconstruction algorithm, to build a 3D scene representation that minimizes the intensity error between a particular frame and its prediction. 3D scene geometry is exploited to remove the visual redundancy between frame pairs for any predictive coding scheme. This approach associates the rate increase with the quality of representation, and is shown to be rate-distortion efficient by the experiments. © 2007 IEEE.
