This dissertation is an exploration on the Gabor filter used in military objects recognition and tracking . Through the analysis of the Gabor function, the properties of the Gabor filter, such as the invariation of scale, rotation and translation, were validated from both aspects of the theory and the experiments. Based on the analysis of the response values that were output from the Gabor filter, the local maximum values were found by using an adaptive window. And these local maximum points were taken as t...
