MODIFICATION OF CATEGORICAL-ZONE METHOD FOR DIGITAL WATERMARKS EMBEDDING
Abstract
Modifications of the categorical-zone method for embedding information into image container were
proposed. Designed modifications are to determine the image blocks contrast type in accordance with the proposed approach;
categories blocks setting by pseudo-random method of masking pixel blocks; control check bits embedded messages
through which excludes blocks which are not suitable for embedding. The software realization and experimental
research of the proposed approach was described.
