An Adaptive Image Steganography Method Based on Histogram of Oriented Gradient and PVD-LSB Techniques
Pixel value differencing (PVD) and least significant bit substitution (LSB) are two widely used schemes in image steganography. These two methods do not consider different content in a cover image for hiding the secret data. The content of most digital images has different edge directions in each pi...
