Stego-Scheme for Secret Communication in Grayscale and RGB Images

Classification, Analysis and Comparison of Non-Blind Image Quality Measure

“…For evaluating the results and performance, different operations are performed on the original, unmodified, input image and then these modified images are compared with input images for image quality. Operations include the following: [14,15,16,17,18,19,20]  LSB Matching [21]  LSB Substitution [22] …”

Experimental Analysis and Review of "Increased Capacity of Information Hiding"

“…Instead of hiding message sequentially in the LSB [2,3,4,5,6] of pixels of an image, as in case of LSB substitution, this method uses the substitution method dynamically and increases the embedding capacity. Important characteristics of this method are summarized as:…”
