Point target detection based on wavelet and pixel value changing
When the impending antiship cruise missile's motion vector alines with the axis of IR detection system, it is difficult to detect and track it by its trace analysis. A novel spatio-temporal filtering method is presented, which employs wavelet analysis and pixel value changing measurement. The images used in the experiments are composed of some real pictures and man-made point target (signals,) and the method is proved to be with high accuracy and sensitivity and low false alarm rate.
