- W2367618881 abstract "This paper puts forward a digital watermarking algorithm for 3D models based on DCT intermediate frequency.The algorithm used the distances between the center of the model and the vetice on the 3D model surface.First,we transform the sequence of distance to signal in frequency domain using one-dimensional DCT.Then we embed watermark into the intermediate frequency coefficients of signal,and then transform the digital signal back to spatial domain using inverse DCT.Experiments show that this algorithm has beter transparency,and is simple to implement,and robust against mesh simplification,cropping,random noise and so on." @default.
