An Algorithm for Digital Image Watermarking using 2-Level DWT, DCT and QR Decomposition based on Optimal Blocks Selection
Digital image Watermarking is a way to achieve information security. In this paper, we present an algorithm for digital image watermarking based on 2-level Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and QR decomposition. The watermark embedding process is performed on specific blocks of the host image according to its entropy values. The experimental results show that this algorithm has good features of imperceptibility and it is robust against different attacks.
