Tampering estimation watermarking based on lifting wavelet and chaotic sequence

Tampering estimation watermarking algorithm is proposed based on lifting wavelet and chaotic sequence. The algorithm decomposes the original image into L level integer wavelet based on lifting method, embed spatial location watermark into the first detail coefficients, and embed the estimation water...
