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

Embodiments of the present invention provide an object tracking method and device. The object tracking method includes: acquiring a video; for each frame of an image in at least some frames of the video, using a feedback neural network to detect the pixel-level detection position information of an object contained in the image in the image, and predicting the position information in the image. pixel-level predicted position information of objects contained in other images in at least some of the frames of images; and tracking objects based on the pixel-level detected position information and the pixel-level predicted position information of objects contained in the video. According to the object tracking method and device of the embodiment of the present invention, the object tracking is realized by predicting the position information of the object in other images based on the current image and comparing the position information. This object tracking method is very simple, the calculation amount is small, and can reduce Object tracking error.

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...
