Reversible Data Hiding Based on Histogram Shifting and Directional Embedding
摘要
Abstract
This paper proposes a reversible data hiding algorithm for color images based on difference histogram shifting and directional embedding .The algorithm uses correlation of color components and relationship between Haar wavelet coefficients to decrease difference and increase the peak of difference histogram .The embedding scheme uses multiple embedding method to improve the embedding capacity , embeds data according to the specified extension direction and uses inverse direction to expand the pixel value .Some expansion cancellout each other , thereby reduce the decline extent of image quality .Experimental results show that the embedding capacity is significantly improved while the quality of stego -image is guaranteed .Compared with other algorithms , the whole properties of this algorithm is higher .关键词
