Variance field estimation-based steganographic (VFES) method for RGB colour images

Abstract

A variance field estimation-based steganographic method for RGB colour images is presented. The proposed method uses variance field estimation and the redundancy of approaches algorithm to provide good invisibility and fine detail preservation in the processed stego-images. Experimental results show that the proposed method is a secure steganographic method that provides good image quality and hiding capacity.

Keywords:

• Variance field estimation
