In Halftone Visual Secret Sharing (VSS) scheme, meaningless random shares are encoded into halftone shares taking meaningful visual information which reduces the suspicion of intruders. Most of the halftone visual secret sharing scheme described in literature generate the shares in the form of the halftone image which makes it difficult for intruded to identify the content of the shares, therefore...
This paper proposes a multiple image sharing scheme for secure communication of multiple images. The proposed scheme is applied for digital information data to provide a secure transmission, in such a way that only receiver get appropriate information. The proposed scheme, secretly generates n number of shares for multiple images by applying the matrix multiplication and matrix addition method with...
In this paper, an efficient video coding, based on three-dimensional vector quantization system has been proposed. There are a few contributions of this paper, the proposed technique uses a pyramid code book based model instead of conventional single level code book. According to this model, if a specific motion cannot be matched accurately in higher level code book according to coarse partitioning...
