Artificial Bee Colony (ABC) is a popular swarm intelligence based approach used to solve nonlinear and complex optimization problems. It is a simple to implement and swarm based probabilistic algorithm. As the case of other swarm based algorithms, ABC is also computationally expensive due to its slow nature of search process. The solution search equation of(More)
— Secret data hiding in binary images is more difficult than other formats since binary images require only one bit representation to indicate black and white. This study proposes a new method for data hiding in binary images using optimized bit position to replace a secret bit. This method manipulates blocks, which are subdivided. The parity bit for a(More)
Always user interaction has been one of the most crucial points when evaluating the quality of services. Mobile television is one of the most important services for the users. Problem of broadcast video streams encoded in scalable manner to enable heterogeneous mobile devices to render the most appropriate video sub-streams. Due to more than one layer(More)
