Different methods of standard definition (SD) to high definition (HD) image conversion are compared according to the PSNR criterion. Subjective comparison is difficult as there is almost no quality difference between them. For comparison, an original HD and the correspondent SD images are required. The SD image is up-converted to approximate HD images using various methods and then these approximated images are co Read More

Video surveillance has a growing importance in public safety services. Departments and organizations delivering public safety and security services often need to resort to covertness in their activities. They usually compromise on distance, lens size and light to insure secrecy; these compromises present challenges on the quality and usefulness of the captured video. Moreover, outdoor surveillance systems, especially over long dis Read More

With the increase in mobile devices there is also an increase in demand for IP mobility across networks. Although not created for that purpose, the LISP protocol offers a clean solution for mobility, via an end-to-end map/encap scheme. The solution offered by LISP allows a mobile device to keep its IP address even when changing networks. LISP’s mobility method, however, breaks when the mobile device does not have access to Read More
