A new steganographic method called STABYLO is introduced in
this research work.
Its main advantage is to be much lighter than the so-called
-Highly Undetectable steGO (HUGO) scheme, a well-known state of the art
-steganographic process in the spatial domain.
-Additionally to this effectiveness,
-quite comparable results through noise measures like PSNR-HVS-M
-and weighted PSNR (wPSNR) are obtained.

To achieve the proposed goal, famous experimented

The STABYLO algorithm, whose acronym means STeganography with
Adaptive, Bbs, and binarY embedding at LOw cost, has been introduced
in this document as an efficient method having comparable, though
-somewhat smaller, security than the well-known
-Highly Undetectable steGO (HUGO) steganographic scheme.

-After having introduced with details the proposed method,

+Moreover, we plan to improve the distortion function by integrating
+into a numerical cost the gradient value of this kind of

+version where the distortion that is transmited is either 1 in
+the adaptive strategy or 1,10, 100 in the fixed strategy.

Other steganalysers than the ones used in this document will be
examined for the sake of completeness. Finally, the

Furthermore, we plan to investigate information hiding on other models, such as high frequency for JPEG encoding.
