NOVEL REVERSIBLE DATA HIDING BASED ON DIFFERENCE EXPANSION

Novel reversible data hiding based on difference expansion

A novel reversible data hiding algorithm based on difference expansion called ACD was proposed, which used the so-called adaptive change direction technology.ACD embeds data by expanding the Gift Card differences of neighboring pixel values.In a pair of pixels, a pixel was for reference and the other was for transform.ACD first estimates the type o

Enzymatic Degradation of Azo Bonds and Other Functional Groups on Commercial Silk Dyes by Streptomyces coelicoflavus CS-29

Azo dyes are used for silk textile manufacture, where their decolorization and detoxication are necessary after initial dying in the craft industry.The bio-decolorization efficiency of Streptomyces coelicoflavus CS-29 toward commercial azo blue and red dyes was investigated, analyzing the degradation and adsorption of dye molecules.S.coelicoflavus
