TY - JOUR AU - Samiappan, Dhandapani AU - Ammasi, Krishnan PY - 2010 TI - Robust Image Watermarking Using Discrete Wavelet Transform JF - Journal of Computer Science VL - 7 IS - 1 DO - 10.3844/jcssp.2011.1.5 UR - https://thescipub.com/abstract/jcssp.2011.1.5 AB - Problem statement: Digital Watermarking have gained popularity in recent years as a means of protecting multimedia data from illegal copying and unlawful reproduction. It is mainly used for copyright protection of multimedia data. Approach: In this study an image watermarking algorithm which is blind (do not require the presence of host image for detection) and robust is proposed. Results: The proposed watermarking scheme embeds the watermark in the Discrete Wavelet Transform (DWT) domain. The watermark is a binary logo and is embedded in the subband of the wavelet decomposition. Conclusion: This watermarking scheme is robust to several attacks like JPEG compression, rotation, Gaussian filtering, median filtering, cropping, scaling, sharpening, Gaussian noise and salt and pepper noise.
