Algorithm for reversible watermarking based on location map
摘要
Abstract
This paper presents an algorithm for reversible watermarking based on location map. The host image is divided into blocks, then make sure the kind of every block according to the data magnitude, after that location map and its coding are produced. The watermarking is embedded according to location map and mixed embedding method. Theory and experimental result indicates that this method can meet the different needs by selecting the appropriate parameter. Theoretical analysis and experimental results show that the algorithm is reversible and effective and secure.关键词
