“…Watermarking is done with embedding the watermark in the special middle frequency coefficient sets of 3-levels DWT transformed of a host image, followed by computing 4×4 block-based DCT on the selected DWT coefficient sets. Paper [4] has proposed a nonblind watermarking algorithm based on wavelets and fuzzy logic, which inserts 8 bit grey scale image as a watermark into the 3D model. The algorithm used in this paper embeds the watermark by modifying the wavelet coefficients of the 3 D model at third level and by using Mamdani's fuzzy inference system, thus enhancing the robustness and making it more imperceptible as compared with other existing algorithms.…”

Insertion of a text message, audio data or/and an image into another image or 3D model is called as a watermarking process. Watermarking has variety of applications like: Copyright Protection, Owner Identification, Copy Protection and Data Hiding etc., depending upon the type of watermark insertion algorithm. Watermark remains in the content after applying various attacks without any distortions. The blind watermarking method used in the system is based on a wavelet transform, a fuzzy inference system and a multi-resolution representation (MRR) of the 3d model. The watermark scrambled by Arnold Transform is embedded in the wavelet coefficients at third resolution level of the MRR. Fuzzy logic approach used in the method makes it to approximate the best possible gain with an accurate scaling factor so that the watermark remains invisible. The fuzzy input variables are computed for each wavelet coefficient in the 3D model. The output of the fuzzy system is a single value which is a perceptual value for each corresponding wavelet coefficient. Thus, the fuzzy perceptual mask combines all these nonlinear variables to build a simple, easy to use HVS model. Results shows that the system is robust against affine transformations, smoothing, cropping and noise attacks.

Robust digital watermarking is an evolving research area that has received a large amount of attention and became a practical solution to copyright protection. This paper proposes a robust and imperceptible non-blind watermarking method for high rate embedding into 3D polygonal meshes. Our approach consists of vertices selection, embedding and extracting steps. First, the vertices are selected for embedding if they are greater than defined threshold, and then the watermark bits are embedded directly into each vertex in spatial domain. The main attractive features of this approach are flexibility in data embedding technique and fast computation compared to other recent techniques. The experimental results showed that the proposed algorithm provides high robustness against the most common attacks. The applied attacks include connectivity attacks such as mesh smoothing, and mesh cropping and the geometric attacks such as rotations, uniform scaling and their combinations.
