Abstract :
This paper proposes a binary image digital watermarking scheme based on the combination of discrete wavelet transform (DWT) and vector transform (VT). Experimental results show that this scheme keeps the image quality rather good and has better robustness to common signal processing operations such as adding noise, filtering and JPEG lossy compression.
