Synchronizing Two Frequently-Cited High-Capacity Image Hiding Methods (Modulus-Based Vs. LSB-Based)

This study briefly reviews and then connects a Modulus-based image hiding method published in 2003 and an LSB-based (Least- Significant-Bits) image hiding method published in 2004. Both methods are frequently cited; and the reason is because of their high hiding capacity (the size of the data can be hidden in an image) and low distortion to the host image; along with the benefit of being simple. This study synchronizes the two methods as one simple method so that the PSNR prediction formula of the 2003 method can also be used by the 2004 method to predict the PSNR of the stego image.
