In this paper, a new and an e ective combination of two metaheuristic algorithms, namely Fire y Algorithm and the Di erential evolution, has been proposed. This hybridization called as HFADE, consists of two phases of Di ...

In the field of computer networks, the introduction of SDN has been associated with new concepts. In SDN networks, control plane is separated from the data palne. Traditional networks suffer from difficult configuration ...

Energy is one of the most important criteria in wireless sensor networks. To extend the lifetime and coverage in these networks, researchers are always looking for ways that they can reduce the energy consumption of sensor ...

It's important and necessary to detect and prove the ownership of a digital work in the communication technology era. The purpose of this paper is to propose a digital watermarking scheme for images. In this scheme, first, ...

Due to employ of embedded systems for safety-critical applications and high probability of occurrence transient faults in them as well as increasing popularity of COTS (commercial off the shelf) components, techniques ...

Automatic lip-reading plays an important role in human computer interaction in noisy environments where audio speech recognition may be difficult. However, similar to speech recognition, lip-reading systems also face several ...

For any coherent imaging systems including ultrasound, synthetic aperture radar and optical laser, the multiplicative speckle noise degrades both the spatial and contrast resolution of the image. So, speckle suppression ...
