Digital Watermarking Algorithm Based on BP Four-layer Neural Network
Nian Xiao · 2008
The authors improved the application method of four-layer neural network to digital watermarking technology and chose BP for neural network of DWT transformation as the training mode,which could better realize blind withdraw of watermark.The results show that this algorithm provides high robustness and invisibleness against image processing attacks such as compression,low-pass filtering,adding noise,cropping,rotating and zooming.
