We consider the problem of detecting the presence of hidden data in colour bitmap images. Like straightforward LSB Replacement, LSB Matching (which randomly increments or …
This paper presents an improved firefly algorithm (DyFA) for feature selection that improves the convergence rate and reduces computational complexity through dynamic adaptation in …
