Abstract

The present application discloses a target tracking method and device. The method includes extracting image features in an image target candidate area of ​​a video frame, and outputting an initial response value; smoothing the initial response value of the video frame; and updating the response value to determine the position information of the target in the video frame. The present application solves the technical problem of poor effect of the target tracking method. Through the method of this application, the output response of the network will often appear multi-peak and drift due to complex target states such as scale transformation and sudden movement. By fully considering the similarity relationship between adjacent superpixel blocks of the image, The relationship is used to constrain the initial response value, suppress the drift phenomenon in the tracking process, and then correct the position information of the target. Furthermore, the tracking accuracy and tracking efficiency of the object tracking method are improved.

Description

technical field [0001] The present application relates to the field of computer vision, in particular, to a method and device for object tracking. Background technique [0002] Object tracking is one of the research hotspots in the field of computer vision. It is widely used in practical problems such as video surveillance and human-computer interaction, and has important research value. However, limited by the complexity of the actual environment, such as occlusion, illumination changes, target deformation, and similar background interference, the tracking method of correlation filtering can meet the actual application requirements to a certain extent in terms of accuracy, robustness, and real-time performance. . [0003] The inventors found that, in the tracking method of correlation filtering, a drift phenomenon occurs during the tracking process, which further affects the tracking accuracy. [0004] Aiming at the problem of poor effect of the target tracking method in ...
