High Capacity Image Steganography Using Modified LSB Substitution and PVD against Pixel Difference Histogram Analysis
The combination of pixel value differencing (PVD) and least significant bit (LSB) substitution gives higher capacity and lesser distortion. However, there are three issues to be taken into account: (i) fall off boundary problem (FOBP), (ii) pixel difference histogram (PDH) analysis, and (iii) RS ana...
