Problems solved by technology

However, in the process of tracking, pixel-level detection methods bring additional difficulties due to the irregular shape of given objects due to the need to compare the positional correlation and appearance similarity of detected objects in different frames.

Abstract

The embodiment of the invention provides an object tracking method and apparatus. The object tracking method comprises: a video is obtained; for each frame of image in at least parts of frames of images in a video, pixel-level detection position information, in the image, of an object included by the image is detected by using a feedback type neural network and pixel-level prediction position information, in other images of the at least parts of frames of images, of the object included by the image is predicted; and according to the pixel-level detection position information and the pixel-level prediction position information of the object included in the video, the object is tracked. According to the object tracking method and apparatus, the position information of the object in other images is predicted based on the current image and position information is compared, thereby realizing object tracking. The object tracking way is simple; the calculation load is low; and the object tracking error is reduced.

Description

technical field [0001] The present invention relates to the field of image processing, and more particularly relates to an object tracking method and device. Background technique [0002] The detection and tracking of pedestrians, vehicles and other objects is an indispensable part of many security applications. In existing methods, object detection and object tracking are often divided into two independent links to solve this problem. First, in each frame of the captured video, detect the objects of interest, and express their position and size through the frame, and then divide the detected objects in each frame of the image according to the spatial position, appearance similarity, etc. Objects are linked together so that they can be tracked. In the above two links, it is possible to introduce additional errors. Especially in the detection process, in a crowded environment, the bounding box does not represent the position of the object well. For example, in a crowded c...
