In this paper, a covert communication scheme is proposed for a RS-code-based multiple description image coding system. Firstly, the secret information is embedded in the carrier image by the double-domains based method. And then the carrier image is encoded with the SPIHT algorithm. The SPIHT stream is delivered through the RS-code-based multiple description image coding system to conquer the channel...
In this paper, a covert communication scheme is proposed for a set partitioning in hierarchical trees (SPIHT) based image multiple description coding (MDC) system. Firstly, the carrier image is subsampled into four subimages. The secret information is embedded among the subimages with a discrete wavelet transform (DWT) and subsampling based method. The information embedding method is also proposed...
