- W2350707479 abstract "In this paper,a DEM watermarking arithmetic is proposed which is based on the Hash function,wavelets and wavelets coefficient fuzzy relation.The algorithm extends the visual system of quantization noise in wavelet domain analysis of visual weight,so it can be used in DEM data.The matrix of fuzzy relation is image-adaptive,and this watermarking is a kind of blind watermarking.The watermarking combines with classical cryptology arithmetic.DEM data embedded Watermark and no embedded are no difference in visible.The watermarking is non perceptible and safety,so it is effective method to protect DEM data." @default.
