Digital watermarking algorithm for color images based on HVS and DWT
Tang Xiao · Microcomputer & its Applications · 2010
A digital watermark algorithm by embedding a color digital watermark into an original cplor image was discussed. The algorithm inserted the watermarks into the middle-low frequeny subbands in odd rows and columns after DWT according to HVS,The method was tested with attacks such as cropping,polluting and noise adding,obtaining results of good robustness and low visual distortion.
