摘要 本文基于图像隐藏和双随机位相编码技术提出了一种隐蔽传递信息的方法 ,可以把一幅或多幅需隐蔽传递的图像经双随机位相编码后隐藏在另一幅任意选取且足够大的宿主图像中。而在恢复隐蔽图像时 ,可直接对携带隐藏信息的融合图像进行处理 ,不需要利用原始宿主图像 ,且重构图像的质量较好 。 Based on image hiding and double-random phase encoding techniques,a method for transmitting data secretly is presented.One or several double-random phase encode images that need to be transmitted secretly can be hided in a large host image selected at random.When need to decode,operation can be applied on the composed image directly and no original host image will be needed.The quality of the reconstructed image will be quite well and be not influenced by the host image.
