A Robust Method for Data Hiding in Color Images
In this paper, we propose a methodology for embedding watermark image data into color images. At the transmitter, the signature image is encoded by a multiple description encoder. ...

Multiple Description Coding for Image Data Hiding in the Spatial Domain
In this paper, we develop a robust image data hiding scheme based on multiple description coding of the signature image. At the transmitter, the signature image is encoded by balan...
