MLSB optimal effective weighted container construction for WF5 embedding algorithm

Abstract

This paper proposes a multilevel digital watermarking method (WF5) research concentrated on weighted container structure. The primary goal of the research is to find the way how to construct an optimal, efficient weighted container to make an embedding errors invisible. Two types of effective weighted container structures were investigated for color digital images: One Pixel-One Codeword (OP-OC) and One Pixel-Two Codeword (OP-TC) constructions. For both approaches, efficient weighted container structures (masks) that correspond with the Human Vision System (HVS) model were developed, and efficiency of WF5 Multi-Level Significant Bit (MLSB) information embedding algorithms were investigated for different types of digital images.
