In this paper, a novel hybrid scheme with constrained Unequal Error Protection (UEP) and data hiding is proposed which maximizes the perceptual quality of the video at the end user to compensate for the effects of channel losses. The technique involves (1) implementing a forcing function which weighs the objective perceptual quality of the video frame based(More)
In this work, the detector performance of a watermark-based error concealment (WEC) system proposed in C.B. Adsumilli is mathematically analyzed. The spread spectrum based WEC algorithm embeds a low resolution version of an image in itself during encoding. At the receiver, this embedded watermark is extracted and used as a reference to conceal the(More)
