Abstract

The invention discloses a visual tracking method and system for regional suggestion prediction of a multi-view expert group. The method comprises the following steps: acquiring a to-be-tracked video; wherein a first frame of image in the video to be tracked is provided with a target area frame of the object to be tracked and an area frame which is twice as large as the target area of the object to be tracked; based on the region frame of the first frame image, training a classifier to obtain a trained classifier; based on a multi-expert model, performing feature extraction on the ith frame of image of the to-be-tracked video to obtain an optimal feature; wherein the value range of i is 2-N; n is a positive integer; inputting the optimal feature into the trained classifier, and outputting to obtain a rough positive sample candidate frame; and obtaining an optimal candidate frame based on the rough positive sample candidate frame. And a network prediction learning tracker and a multi-view multi-expert repair scheme are suggested by a bridging region, so that the tracking performance can be cooperatively improved.

Description

technical field [0001] The present invention relates to the technical field of visual tracking, in particular to a visual tracking method and system for region suggestion prediction of a multi-view expert group. Background technique [0002] The statements in this section merely mention the background technology related to the present invention and do not necessarily constitute the prior art. [0003] Visual tracking is given an initial object marked with a bounding box in the first video frame, and localizes the object in subsequent video frames. Visual tracking has always been a hot research topic in the field of computer vision, and has a wide range of applications in video surveillance, video retrieval, sports video analysis, etc. Due to the existence of several unique characteristics of target tracking, it has been studied in depth, such as: tracking instability caused by severe deformation of objects, object rotation, severe occlusion, and lighting changes in video fr...
