Abstract: In computer graphics, mesh decomposition is a fundamental problem and it can benefit many
applications. In this paper, we propose a novel mesh decomposition algorithm using motion
information derived from a given animation sequence. The proposed algorithm first use
principal component analysis (PCA) to construct a compact representation of a given
animation sequence. Next, from this representation, we derive several motion parameters
including motion complexity and similarity. Finally, we decompose a given mesh into submeshes
using derived motion information and subdivide the triangles along the cutting paths
for the smoother borders between the mesh parts. Our experimental results show that this
new decomposition scheme can bring the benefit of good compression ratios on animation
sequences.
