... when the channel becomes noisier, whereas the other methods collapse. This is due to the exploitation of adaptive slice grouping which improves the performance of error concealment methods and ... scheme is superior to the method in [5 ]and the other variants of the full scheme. When the transmission is error free, the proposed full scheme has lower performance due to the app...

... greatly reduced. Thanks to the robust component of the algorithm, the HR image also shows no trace of dead pixels, which appear abundantly in Figure 8(a) as highly dark and bright pixels. To better ... mechanism like the Delaunay triangulation [15]. Another drawback of these methods is that they ignore the fact that natural images are often comprised of directional structures, an...

... in the plane of Fig. 3c), which has not been adsorbed by H. The charge around the H atom at the Si adatom removes toward the adsorbed Ag atom and forms a covalent-like Ag -H bond. Due to the charge transfer ... using the same calculation methods, we also obtain the charge distribution associated with the most stable adsorption of Ag at H 3 sites on 1 9H- Si(111)-7 9 7 surface (i...
