IMAGE STEGANOGRAPHY USING BLOCK COMPLEXITY ANALYSIS
Gowtham Dhanarasi, A. Mallikarjuna Prasad · 2012
A block complexity analysis for transform domain image stegonagraphy is introduced in this paper. The algorithm proposed here works on the wavelet transform coefficients which embedded the secret data into the original image. The technique implemented which are capable of producing a secret-embedded image that is indistinguishable from the original image to human eye. This can be achieved by retaining integrity of the wavelet coefficients at high capacity embedding. This improvement to capacity-quality trading –off interrelation is analyzed in detailed and experimentally illustrated in the paper.
