Abstract: The embodiments of the present invention provide a video tracking method, a video tracking device, an object recognition method and an object recognition device. With the devices and methods of the invention adopted, the problem of tracking object loss caused by the discontinuation of the tracking process of an existing video tracking method, and the problems of complex process and low efficiency of an existing object recognition method can be solved. The video tracking method includes the following steps that: a first tracking target in a video is determined, and video tracking is performed on the first tracking target based on the video; the area overlapping degree of the first tracking target in a current image and a first tracking target in a previous image in a video tracking process is calculated, wherein the previous image is an image obtained when the first tracking target was tracked recently before the first tracking target is tracked in the current image in the video tracking process; and the feature information of feature points of the first tracking target object in the video is extracted in the video tracking process of the first tracking target object.
