Small Moving Target Detection based on the Concept of Entropy Flow
نویسندگان
چکیده
The detection of small moving targets under motorial background is very difficult. In order to solve this issue, a novel detection algorithm is presented in this paper, which is based on the concept of entropy flow. Firstly, the concept of entropy flow is used to measure image motion; Secondly, 2-dimensional histogram of flow field is applied to estimate the background motion; Finally, the targets are obtained by using pipeline filtering in difference image. The experiment results demonstrate that the proposed algorithm is appropriate to detect small targets under moving backgrounds, and the algorithm provides an instructive approach to the detection of small targets.

Target Detection in Bistatic Passive Radars by Using Adaptive Processing Based on Correntropy Cost Function
In this paper a novel method is introduced for target detection in bistatic passive radars which uses the concept of correntropy to distinguish correct targets from false detections. In proposed method the history of each cell of ambiguity function is modeled as a stochastic process. Then the stochastic processes consist the noise are differentiated from those consisting targets by constructing...

Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...
