This paper proposes a robust algorithm for detecting interest points based on the NonsubSampled Contourlet Transform (NSCT). The NSCT provides multiscale decomposition with directional filters at each scale. Furthermore, NSCT is very efficient in extracting the geometric information of images and therefore it has very good feature localization. The NSCT-based point detector is compared to the widely used Harris and Difference of Gaussian (DoG) interest point detectors. The experimental results reveal the robustness of the proposed algorithm to rotation, scale and viewpoint changes.
This paper provides a strategy for supervising the motion of some mobile robots that evolve in the same environment. Some regions of the environment are assumed to have a limited capacity in terms of the number of rob...

Source Routing allows a node in the path of a packet to specify partially or completely the route taken by that packet. The route is appended to packet header as a list of nodes to traverse, therefore making simple, stateless forwarding decisions. In this paper, we present a novel approach of Source Routing in SDN that uses stacked VLAN tags. Our solution was validated in Mininet using the Ryu controller and proven to have multiple advantages over other forwarding methods.
A novel nonlinear controller that inherently limits the RMS value of a three-phase grid-following inverter current is presented in this paper. Using the dynamic model of the inverter in the rotating dq reference frame...
