| Summary: | 碩士 === 國立中興大學 === 資訊科學研究所 === 92 === Abstract
We present a new steganographic system for 3D polygonal model based on wavelet transform. The message data were embedded in the wavelet coefficients at various resolution levels of the multi-resolution representation (MRR) of the polygonal model. It makes the hiding data imperceptible and invariant to the affine transformation. The data capacity is large and can be blind extracted with the embedding key.
