Abstract
A method for identifying a target object in a video file is implemented using an identification system. In the method, the identification system is programmed to: obtain a video file and an image; obtain a target object in the image; construct an image model based on a feature of the target object; extract key frames from the video file sequentially; perform a comparing procedure for each key frame to determine whether the key frame includes a similar object corresponding to the image model; and for each key frame, extract from the key frame, when the determination is affirmative, a part of the key frame that contains the similar object to obtain a target image, presence of the target image indicating that the target object is identified in the video file.
