摘要
给出了基于投影寻踪学习网络的数字图像盲水印嵌入和提取的方法.通过实验比较了相同隐节点下使用投影寻踪学习网络、BP神经网络和RBF神经网络进行训练嵌入水印的效果,结果表明使用投影寻踪学习网络实现水印技术具有有更强的实用性.
Based on projection pursuit learning network, a color image blind watermarking method was presented. And we compared the effect for watermark extracted that using PPLN, BP neural network and RBF neural network to embedding watermark with same number of hidden node. The experiments show that using projection pursuit learning network in watermarking technology has better practicability than other neural network.
