The Use of Watermarking in Stereo Imaging
Dinu Coltuc · IGI Global eBooks · 2011
The manipulation and processing of stereo image sequences demand higher costs in memory storage, transmission bandwidth, and computational complexity than of monoscopic images. This chapter investigates scenarios for cost reduction by using reversible watermarking. The basic principle is to embed some data by reversible watermarking instead of either computing or storing/transmitting it. Storage and/or bandwidth are reduced by embedding into one frame of a stereo pair the information needed to recover the other frame. Computational complexity is reduced by embedding the disparity map. The cost of extracting the embedded disparity map is considerably lower than the one of computing it. Experimental results are provided.
