- W2347286377 abstract "The watermark based on Tchebichef moments and wavelet lifting is used in an authentication context.After the discrete lifting wavelet transform,the lower order Tchebichef invariant moments of the sub band coefficients are computed.The processing of the encoder and the decoder is simple,and a few low order moments need to be calculated.The algorithm is compared with the algorithm based on the geometric moments.Results show that the scheme is simple,effective.It has high stabilities of geometrical attacks of rotation,scaling,shearing,and JPEG compression." @default.
