High capacity steganographic method based upon JPEG [PDF]

open access: yes, 2008
The two most important aspects of any image-based steganographic system are the quality of the stegoimage and the capacity of the cover image. This paper proposes a novel and high capacity steganographic approach based on Discrete Cosine Transformation (

JPEG steganography: A performance evaluation of quantization tables [PDF]

open access: yes, 2009
The two most important aspects of any image based steganographic system are the imperceptibility and the capacity of the stego image. This paper evaluates the performance and efficiency of using optimized quantization tables instead of default JPEG ...

Rate-controlled, region-of-interest-based image coding with JPEG-LS [PDF]

open access: yes, 2003
Since the standardization of JPEG-LS, several improvements and variations to the original algorithms have been proposed. In this paper we propose a Region of Interest (ROT) based coding strategy for JPEG-LS that has the additional ability of providing ...
