Color stereo embedding by reversible watermarking

By embedding into the three color channels of a stereo frame the information needed to recover the other frame, the transmission/storage requirements when operating with stereo images are halved. A disparity compensation scheme on each color plane is used. Due to the reversibility of the watermarkin...

Description
Summary:By embedding into the three color channels of a stereo frame the information needed to recover the other frame, the transmission/storage requirements when operating with stereo images are halved. A disparity compensation scheme on each color plane is used. Due to the reversibility of the watermarking, the embedded frame is recovered exactly. The quality of the recovered frame depends on the embedding bit-rate of the reversible watermarking method and of the information size needed to be embedded. The experimental results obtained so far on high quality color images are very good.
