Abstract

The invention provides a target tracking model training method and device. The training method of a target tracking model comprises the follwoiing steps of training a target tracking model based on asample image pair, wherein the sample image pair comprises a template image and a search image; wherein the search image is marked with a classification label and a weight label corresponding to a pixel point of the search image; the method comprises the following steps: carrying out iterative training by utilizing the following steps until the model training requirements of a target tracking model are met: inputting a sample image pair into the target tracking model, and predicting based on the target tracking model to obtain the similarity between a search image and a template image; determining similarity loss of the iteration according to the similarity, the classification label and the weight label; and updating model parameters of the target tracking model according to the similarityloss. The accuracy of target tracking can be improved.

Description

Technical field [0001] This application relates to the field of artificial intelligence, and in particular to a method and device for training a target tracking model. Background technique [0002] Target tracking technology is an important branch in the field of computer vision, and has very important research significance. It has broad application prospects in many aspects such as video surveillance, robot vision navigation, human-computer interaction, and medical diagnosis. Target tracking refers to the detection, extraction, recognition and tracking of moving targets in an image sequence to obtain the motion parameters of the moving target, such as position, speed, acceleration, and motion trajectory. [0003] During target tracking, since the target is generally moving, it is prone to occlusion, pollution, or deformation of the target. For example, the target occlusion can be a situation where a part of the pedestrian's body is blocked by a tree, a car, or a building when the...
