Abstract: |
|
In this paper,
we present a new surface content completion system that can effectively
repair both shape and appearance from scanned, incomplete point
set inputs. First, geometric holes can be robustly identified
from noisy and defective data sets without the need for any normal
or orientation information. The geometry and texture information
of the holes can then be determined either automatically from
the models¡¯ context, or interactively from users¡¯ selection. We
use local parameterizations to align patches in order to extract
their curvature-driven digital signature. After identifying the
patch that most resembles each hole region, the geometry and texture
information can be completed by warping the candidate region and
gluing it onto the hole area. The displacement vector field for
the exact alignment process is computed by solving a Poisson equation
with boundary conditions. Our experiments show that the unified
framework, founded upon the techniques of deformable models, local
parameterization, and PDE modeling, can provide a robust and elegant
solution for content completion of defective, complex point surfaces. |
