This paper discusses the approach to construction of steganographic method for the weighted container. To find the efficient solution, concept of Penalty Function is introduced. The analysis of the efficiency of the weighted embedding for the simple model of weighted container is shown.
Based on the investigation of 42 persons with Alzheimer's disease, it has been shown that in spite of absence of changes in the sum of apoB-containing fractions of lipoproteins a redistribution of their particles is observed suggesting adverse shifts in the processes of direct transport of lipids. These patients also manifest disturbances of the reverse… (More)
The secure digital watermarking method for digital images is proposed. This method is based on error correcting codes (ECC) that are perfect in weighted Hamming metric. The usage of perfect ECC guarantees the limited number of errors (distortions of initial image) that occur in watermarking process. The use of ECC that are perfect in weighted Hamming metric… (More)
The algorithm of fingerprint constructing for still images based on weighted image structure model is proposed. The error correcting codes that are perfect in weighted Hamming metric are used as a base for fingerprint constructing.
Twenty six patients, used home-made ephedrine like psychostimulators were examined. Nervous system pathology in these cases was characterized by short (several months) period of the pathological process formation, young patient's age, absence of family psychiatric history, pronounced systemic and multilevel affection of the organism, severity of psychic… (More)
The paper presents a study of efficiency of information embedding in BMP images by using codes perfect in a weighted Hamming metric (WHM) and standard Hamming codes. The weighted container model and modification of algorithm F5 is used, which allows to record information in multiple bit planes images (MLSB), taking into account the significance of each bit… (More)
The comparison of efficiency of two such approaches LEBC embedding method and Weighted F5 embedding that are used for weighted structures of container and F5 method that is used for least significant bit(LSB) embedding is made. The comparison metric was found for correct comparison of weighted and unweighted syndrome coding embedding. As a result the… (More)
