(a)-(g) Progressive Denoising; (h)-(i) Progressive Smoothing Abstract —Most of the
existing methods for mesh denoising concentrate on models where all the
vertices in the mesh are corrupted with low noise amplitudes i.e. either
for fine scale mesh denoising or mesh smoothing. Some of these existing
techniques would not serve the purpose of denoising even when a small
percentage of the vertices are corrupted with noise of very high
amplitude. To tackle this predicament, we propose a very efficient,
systematic and an iterative mesh denoising procedure for such models in
which a particular percentage (as high as 70%) of the vertices are
corrupted with both high and low noise amplitudes. It is a two phase
mechanism, where the corrupted vertices are first detected in the
primary phase by means of a proposed Localized Co-ordinate Variation
(LCV) filter. In the subsequent phase, the detected corrupt vertices in
the first phase are eliminated by interpolating the co-ordinates of the
neighboring noise-free vertices with Cardinal Splines. The proposed
algorithm is also coupled with an existing Vertex-Based Anisotropic
(VBA) mesh smoothing algorithm which ameliorates the quality of the
reconstructed mesh obtained after simulating the proposed algorithm.
Promising results have been shown to support all the above mentioned
claims in this work. The work is to be revised properly and submitted
for a peer review in the Springer Transactions on Visualization and Computer
Graphics. The results related to this work are shown in the above
figures.
