- W2390997145 abstract "A watermarking algorithm based on 2D-barcode and HVS is proposed in this paper.A structured 2D-barcode,PDF417,is used as watermark.In order to reduce the embedded watermarking barcode information,the 2D-barcode is pre-handled before embedded through omitting start and stop characters,deleting blank border region in the barcode,reducing barcode's modules and scrambling the barcode based on chaotic sequence.A mask of the source image is modulated based on wavelet transform.Based on the human visual masking of choice,the region with the most abundant texture is selected and the watermark is embedded.This method is a blind watermarking algorithm because resuming the start and stop characters of the barcode,extracting and detecting are independent of any original information.The watermarking structure and embedded algorithm enhance the robustness of the watermark.They also strengthen the resistance of system for various attacks on the watermark." @default.
