Discrete wavelet transform (DWT) is the most widely used in signal analysis due to its fast, simple, memory efficient characteristics. On the other hand, due to the fast development of the digital media information processing technology, three dimensional models (3DM) are more and more utilized in medical, industrial and entertainment fields. In contrast, 3DMs are also easy to be transmitted and duplicated...
The previously published three dimensional models (3DM) watermarking schemes have always involved different (i.e. non-standardized) algorithms for watermarks embedding and the subsequent recovery of the attacked watermark embedded 3DM (for watermark extraction). If a 3DM watermarking algorithm does not have standardizing and stable steps to resort the 3DM vertices, the extracted watermarks from a...
