Adaptive digital watermarking algorithm under image quad-tree partition
An adaptive digital watermarking algorithm based on image quad-tree partition was proposed.The original image was approximated by various least square polynomial patches at multiple scales and was organized by a quad-tree structure.At the same time,this representation also reflected the texture info...
