A PDE patch-based spectral method for progressive mesh compression and mesh denoising
The development of the patchwise partial differential equation (PDE) framework a few years ago has paved the way for the PDE method to be used in mesh signal processing. In this paper, we, for the first time, extend the use of the PDE method to progressive mesh compression and mesh denoising. We, meanwhile, upgrade the existing patchwise PDE method in patch merging, mesh partitioning, and boundary extraction to accommodate mesh signal processing. In our new method, an arbitrary mesh model is partitioned into patches, each of which can be represented by a small set of coefficients of its PDE spectral solution. Since low-frequency components contribute more to the reconstructed mesh than high-frequency ones, we can achieve progressive mesh compression and mesh denoising by manipulating the frequency terms of the PDE solution. Experimental results demonstrate the feasibility of our method in both progressive mesh compression and mesh denoising

A PDE Patch-based Spectral Method for Progressive Mesh Compression and Mesh Denoising
YesThe development of the patchwise Partial
Di erential Equation (PDE) framework a few years a-
go has paved the way for the PDE method to be used
in mesh signal processing. In this paper we, for the rst
time, extend the use of the PDE method to progressive
mesh compression and mesh denoising. We, meanwhile,
upgrade the existing patchwise PDE method in patch
merging, mesh partitioning, and boundary extraction
to accommodate mesh signal processing. In our new
method an arbitrary mesh model is partitioned into
patches, each of which can be represented by a small set
of coe cients of its PDE spectral solution. Since low-
frequency components contribute more to the recon-
structed mesh than high-frequency ones, we can achieve
progressive mesh compression and mesh denoising by
manipulating the frequency terms of the PDE solution.

denoising
