Embodiment Construction

[0010] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0011] figure 1 A self-resilient object tracking method based on multi-level feature extractor is shown, which utilizes feature extraction network (VGG) and multi-scale feature pyramid network to extract features from input images or videos, and then generates features based on the learned features. Dense bounding boxes and classification scores are subjected to non-maximum suppression operations to generate final results.

[0012] Specifically, the feature extraction network is composed of a feature fusion module, a U-shaped module and a multi-scale feature recombination network; the feature fusion module is composed of a feature fusion module 1 and a feature fusion module 2, and the feature fusion module 1 through the fusion backbone The feature map enriches semantic information as basic features (VGG); the U-shaped module has three groups, ...

Abstract

The invention discloses a multi-stage feature extractor-based target tracking method with self-restoring force, which is characterized by comprising the following steps of: extracting features from an input image or video by using a feature extraction network and a multi-scale feature pyramid network; and generating a dense bounding box and a classification score according to the learned features, and carrying out non-maximum suppression operation to generate a final result. According to the multi-level feature extractor-based target tracking method with the self-restoring force, the image feature pyramid is constructed by using the multi-scale features extracted by the multi-level feature extractor, so that the problem caused by the scale change of the tracking target is relieved, and the method has relatively high target recognition accuracy and relatively high target tracking speed; moreover, the method is high in robustness, has the self-recovery capability, and is higher in application value in the fields of target tracking, video monitoring and the like.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a target tracking method with self-resilience based on a multi-level feature extractor. Background technique [0002] Target tracking is a research hotspot in the field of computer vision, and it has high application value in the fields of cloud tracking, UAV, intelligent target tracking, and intelligent transportation. In real applications, since the tracked object and the tracking device are always in relative motion, the scale of the tracked target in the captured image is always changing, and the drastic change usually leads to a change in the detection rate of the algorithm. Low, affects target tracking. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a target tracking method with self-resilience based on a multi-level feature extractor, which can alleviate the problem caused by the change of the tracking target sc...
