Due to the ease with which convincing digital image forgeries can be created, a need has arisen for digital forensic techniques capable of detecting image manipulation. Once image...
The enhancement of compressed video is considered. We present a general algorithm for processing the compressed data, with three variants of the algorithm having practical applica...
We propose a new multiple description method for wavelet transform coded images. The partitioning of the coefficients at the encoder is combined with concealment at the decoder to...
