A Blind Digital Image Watermarking Method Based on the Dual-Tree Complex Discrete Wavelet Transform and Interval Arithmetic

Abstract

We propose a new digital image watermarking method based on the dual-tree complex discrete wavelet transform (DT-CDWT) and interval arithmetic (IA). Both the DT-CDWT and IA produce redundancy from the original data. This implies that there is a possibility of developing a new watermarking method based on the DT-CDWT and IA. We describe our watermarking procedure in detail and show experimental results demonstrating that our method gives watermarked images that have better quality and that are robust against attacks such as marking, clipping, JPEG and JPEG2000 compressions, median filtering, addition of Gaussian white noise, addition of salt & pepper noise, rotation and resizing.
