Abstract:

In order to improve the compression efficiency on geometry image sequences, this paper improves a lossy compression method based on thin plate spine(TPS). In
this method, this paper utilizes the feature of TPS transformation that can be used to take shape deformation on 3D surfaces. The TPS transformation is used as the predictor
from one frame to the next frame of each adjacent frames, then coded the predicted frames through storing transformational matrices of TPS transformation. This paper applies the
method on a geometry image sequence of 3D facial meshes, and achieves good compressing performance.

Key words: geometry image sequence, 3D meshes compression, lossy compression, 3D facial expression model, TPS
