- W2370067411 abstract "To avoid the drawback of difference histogram shifting algorithm which has lower capacity and image quality in multi-embedding,a reversible data hiding algorithm for color images based on wavelet coefficient difference histogram shifting is proposed in this paper.This algorithm uses the correlation of color components and the relationship between wavelet coefficients to decrease difference.The histogram of difference is more compact,and the peak is larger.The embedding scheme makes use of dual-embedding method to increase the embedding capacity,and uses the reverse direction to expand the pixel value.The maximum expansion is 1,and some expansions cancel out each other,so the stego-image quality is higher.Experimental results show that the embedding capacity and the quality of stego-image are significantly improved compared with other new or classical algorithms." @default.
