By accurately estimating the noise shape from diversity, the detector is noise adapted and optimal detection will be achieved. The trade-off caused

An efficient algorithm searching for the synchronization parameters has been developed. Using multi-resolution coarse-fine searching to prune the searchin

In HVS, the response of visual cortex decomposes the image spectra into perceptual channels that are octave bands in spatial frequency. Based on the octave-bands division, same numbers of bits of the watermark are inserted
