RE: [WM]:Reversible Data Hiding Algorithm

["Tian Jun \(Princeton\)" <Jun.Tian@thomson.net>]

Siamak and Xiao-Ping, 

I would like to draw your attention to a recent paper by Kamstra and Heijmans, "Reversible data embedding into images using wavelet
techniques and sorting", IEEE Transactions on Image Processing, Volume 14, Issue 12, Dec. 2005 Page(s):2082-2090. They presented an
improved difference expansion algorithm, which is among one of the highest perceptual quality at a given embedding bit rate. 

Have fun.

Hi Xiao,
  =20
  I read your nice paper and  your method. Since my method outperforms = = the Tian method that you compare in your paper, it also
outperforms your method.

  Thank you very much for your advice.
  With Best Regards,
