Problems solved by technology

[0004] Aiming at the deficiencies of current target tracking methods based on correlation filtering, the purpose of the present invention is to provide a correlation filter update device that considers scene classification in target tracking. The scene adaptively updates the correlation filter to improve the accuracy of tracking, and uses discrete Fourier diagonalization to reduce the complexity of storage and calculation

Embodiment Construction

[0019] The present invention is elaborated below in conjunction with accompanying drawing:

[0020] Such as figure 1 As shown, a correlation filter updating device considering scene classification in target tracking of the present invention includes the following modules:

[0021] The target block module is used to block the tracking target area, and the obtained small blocks will be used for the subsequent determination of the scene where the target is located;

[0022] The acquisition parameter module is used to process the overall response value and the small block response value of the tracking target in the previous frame and the current frame image, and obtain the similarity parameters to be used for subsequent determination of the scene where the target is located;

[0023] The scene determination module where the target is located is used to determine the scene where the tracking target is located in the current frame;

[0024] The adaptive learning update module is ...

Abstract

The invention discloses a coherent filter updating device considering scene classification during target tracking. The device comprises a target blocking module, a parameter acquisition module, a target scene judgment module and an adaptive learning updating module. In a practical target tracking process, many realistic conditions will impose influences, e.g., a target deforms or is sheltered, particularly long-time big-area sheltering happens; and due to the fact that existing coherent filters have limited understanding on the scenes, the performance of a tracker will be substantially lowered. In order to improve tracking robustness, the adaptive learning updating device is arranged, a coherent filter is subjected to adaptive updating according to different scenes of the target, and the influences of long-time big-area sheltering, appearance changes of the target and other different scenes on tracking performance are solved.

Description

technical field [0001] The invention belongs to the technical field of target tracking, and in particular relates to a correlation filter updating device considering scene classification in target tracking. Background technique [0002] Moving target tracking is a very important part of the application in the field of computer vision, and can be applied to various fields such as video surveillance, human-computer interaction, visual navigation, and military guidance. Moving target tracking uses a tracking algorithm to analyze and process video image frames to obtain the position of the target. However, in the actual tracking process, it will be affected by many realistic conditions, so that the real-time performance of the tracking algorithm cannot meet the requirements. [0003] In response to this problem, scholars have applied the idea of ​​correlation filtering to target tracking, which has improved the speed of target tracking. After that, many improved algorithms base...
