Research on Digital Watermarking Algorithm Based on Wavelet Transform Fused with Visual Model

This paper aims to develop a digital watermarking algorithm based on wavelet transform and the characteristics of the human visual system (HVS). The main objective is to leverage the masking characteristics of HVS and the time-frequency localization properties of wavelet transform to achieve efficient watermark embedding. The goal is to ensure that the watermark is imperceptible to the human eye while maintaining the robustness and embedding strength of the watermark. This research contributes to enhancing the practicality and reliability of digital image processing and information security technologies.
