Abstract


The infrared image small target detection is one of the key techniques of infrared search and track system , using infrared images to achieve the goal of automatic detection , identification and tracking is the main direction of development in modern military weaponry . Infrared sensors can easily be atmospheric thermal radiation , long-distance and sensor noise often present in the dark with the goal , even as a point target , target submerged in the infrared image noise detected . The infrared image small target detection is one of the key technologies in military weapons systems . Has become an important factor to decide the victory or defeat of modern warfare . The longer and less goals, targets the imaging area , the probability of a larger distance affect the target from background and clutter , comparative law and other topics in the detection field and track small targets can be powerful detection and tracking complex background , has become more realistic and challenging research topic . The infrared image small target detection and tracking of moving complex background algorithm is studied in this paper . Main work can be summed image preprocessing , target detection and tracking of condensate filter has been in the field of target tracking because it has strong nonlinear target motion and non - additive Gaussian noise is prominent . Conventional filters , such as tracking Kalman filter , have been well studied linear tracking application , but performed poorly nonlinear applications . The condensate filter has been shown to perform nonlinear applications . The condensate filter method is computationally intensive , advances in processor speed and computing power has led to the application of this method of tracking . This paper discusses the use of a filter to keep track of the condensation in the noisy image small target . And compare the results with the Kalman filter .
