An Adaptation of GRA Method for Network Selection in Vertical Handover Contextpt (Always Best Connected). We can count several wireless networks technologies, namely 3GPP (GPRS, UMTS,?...), Wi-Fi technologies, and WiMAX. In such heterogeneous environment, the mobile device must ensure a seamless vertical handover (VH), which means the switching of communication between differ

Abdeljalil Elouardighi,Hafdalla Hammia,Mohcine Maghfourto synthesize arbitrary virtual views from color-plus-depth 3D data. In this work, a novel semi-blind watermarking scheme is proposed to protect DIBR 3D images. The watermarking system utilizes image descriptors as side information to compensate the distortion produced by DIBR operations. The compen

Here, a novel technique that is both reversible and robust is proposed for hiding data in audio. It is perfectly reversible for unmodified stego signals and is semi-reversible for perceptually coded stego signals. A robu

Utilizing the similarity between two frames in a stereo image pair the required size of storage and transmission bandwidth for the stereo image pair can be reduced to 50?%. A residual error matrix with a dynamic range of [?255, 255] is obtained

However, only a few works have been reported on the detection of image sharpening. From a perspective of texture analysis, the over-shoot artifact caused by
