Застосування методів матричного кодування при стеганографічному вбудовуванні даних в зображення

Abstract

When it comes to practical application of image steganography methods it is common to observe distortions which appear due to the fact that the required amount of information to embed (i.e. payload) does not agree with the actual capacity of the stego-container or due to the need of providing a higher embedding threshold for accurate (error-free) decoding of steganographically embedded information on the receiving side. The distortions of the stego-container caused by embedding can be significantly reduced by employing methods of adaptive embedding. This paper analyses the feasibility of matrix encoding as one of the methods to perform adaptive stego embedding.
