Method for detecting specific kind objective in movement scene in real time

Abstract

The invention provides a method for detecting a specific kind objective in a movement scene in real time. The method includes the steps that single-frame significance detection is conducted on an obtained video frame sequence, and a significance area which most probably comprises a suspected objective is obtained; an offline training deep learning specific objective classifier is used for conducting target classification judgment on various significance areas, and the property of each significance area is determined; after a concerned specific kind objective is found, a current frame significance detection result serves as the start, and tracking and recording of the subsequent movement track of the objective are achieved. According to the method for detecting the specific kind objective in the movement scene in real time, on the condition that a camera bearing platform moves, the significance areas with few suspected objectives are rapidly determined based on a single-frame image, the calculated amount of full figure searching is reduced, and the algorithm meets the condition of real-time calculation. An adopted deep reliability network has multiple implied layers, has the more excellent feature expression capability than a superficial network and still has the superior classification performance on target images with greatly-changed illumination and appearances.
