This paper investigates the application of lossy distributed source coding to high resolution multispectral images. The choice of distributed source coding is motivated by the need for very low encoding complexity on space and airborne platforms. The data consists of red, blue, green and infra-red channels and is compressed in an asymmetric Wyner-Ziv setting. One image channel is compressed using...
R. Crandall introduced in the matrix encoding idea to improve the embedding efficiency for steganography. The steganographic algorithm F5 proposed by Westfeld is the first implementation of the matrix encoding concept to reduce modification of the quantized DCT coefficients. In this paper, a new construction of protocol steganography is considered, it is an extension of the error correcting code and...
