Object tracking in cluttered background based on optical flow and edges
Proceedings of 13th International Conference on Pattern Recognition, 1996 This paper describes a method of determining contours of moving objects in a cluttered scene by integrating optical flow and edges. If the motion of an object is similar to that of the background, the contour is not determined only by optical flow. If the background of a scene is cluttered, the contour is not determined only from edges because many ...

Comparative Study on Chaos Identification of Ionospheric Clutter From HFSWR
IEEE Access, 2019 In addition to target echoes, high frequency surface wave radar (HFSWR) receives sea and ionospheric clutter. Among these clutters, the ionospheric clutter is dominant and significantly affects the detection performance of HFSWR, particularly when the ...

Modified Anderson-Darling Test-Based Target Detector in Non-Homogenous Environments
Sensors, 2014 A constant false alarm rate (CFAR) target detector in non-homogenous backgrounds is proposed. Based on K-sample Anderson-Darling (AD) tests, the method re-arranges the reference cells by merging homogenous sub-blocks surrounding the cell under test (CUT)
