“…The watermarking scheme proposed by Laumar [21] and Anbarasi [20] using Weber's Law shows that the generated watermarked model is similar to the host 3D model for strength factor α equal to 0, whereas the retrieved watermark will be close to original watermark for strength factor α equal to 1. Identifying a strength factor to generate a less visually degraded watermarked model with a good retrieval property was performed using a trial and error method in these schemes.…”

The development of new multimedia techniques such as 3D printing is increasingly attracting the public's attention towards 3D objects. An optimized robust and imperceptible watermarking method based on Ant Colony Optimization (ACO) and Weber Law is proposed for 3D polygonal models. The proposed approach partitions the host model into smaller sub meshes and generates a secret watermark from the sub meshes using Weber Law. ACO based optimized strength factor is identified for embedding the watermark. The secret watermark is embedded and extracted on the wavelet domain. The proposed scheme is robust against geometric and photometric attacks that overcomes the synchronization problem and authenticates the secret watermark from the distorted models. The primary characteristic of the proposed system is the flexibility achieved in data embedding capacity due to the optimized strength factor. Extensive simulation results shows enhanced performance of the recommended framework and robustness towards the most common attacks like geometric transformations, noise, cropping, mesh smoothening, and the combination of such attacks.
