Problems solved by technology

[0003] At present, when the existing technology is used to track moving images, problems such as insufficient lighting and uneven brightness often lead to alternating light and dark in moving images, and unclear targets and backgrounds, which have a significant impact on the accurate identification and tracking of moving targets.
At the same time, when the moving target is tracked through the moving target image information obtained by target recognition, it is easy for the target model to not match the candidate model, resulting in the problem of tracking failure.

Abstract

The invention provides a motion image tracking method and device, and relates to the technical field of image processing. The method comprises the steps: carrying out the illumination equilibrium processing of a motion image; carrying out the recognition of a moving target in each frame of the motion image through employing an inter-frame difference method; carrying out the similarity analysis of the moving targets in two adjacent frames through a Bhattacharyya parameter, and obtaining a moving track of the moving object. The method and device provided by the invention can achieve the processing of images of different scenes at different motion scales, eliminate the interference from background information and motion noise, and improve the accuracy and instantaneity of a moving target recognition and tracking result.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a moving image tracking method and device. Background technique [0002] Moving image tracking is mainly to search the position of the moving target in the image through image processing technology, and realize the tracking technology through the detection and positioning of the target. It has a very wide application prospect in practice, including security monitoring, military applications, medical diagnosis, Intelligent navigation, human-computer interaction, etc. [0003] At present, when the existing technology is used to track moving images, problems such as insufficient lighting and uneven brightness often lead to alternating light and dark in the moving image, and unclear targets and backgrounds, which have a significant impact on the accurate identification and tracking of moving targets. At the same time, when the moving target is tracked through the mo...
