Abstract

The embodiment of the invention provides a video annotation method and device, a tracking method and device, computer equipment and a storage medium. The video annotation method comprises the steps ofdisplaying an inter-frame association relationship between a to-be-annotated video frame and a to-be-annotated video to which the to-be-annotated video frame belongs; receiving first input information used for indicating a labeling result of a to-be-labeled video frame and second input information used for indicating a video frame range using the labeling result, wherein the video frame range isdetermined according to an inter-frame association relationship of the to-be-labeled video; obtaining a labeling result of a to-be-labeled video frame according to the first input information, and obtaining a labeling result of a video frame in a video frame range according to the second input information; respectively calculating mapping matrixes of a previous video frame and a next video frame in a video; multiplying the two mapping matrixes to obtain an inter-frame mapping matrix, wherein the inter-frame mapping matrix reflects the inter-frame offset of the object image between the previousvideo frame and the next video frame.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular, to a video tagging method, a video tracking method, and corresponding devices, computer equipment, and computer-readable storage media. Background technique [0002] With the development of artificial intelligence technology, various machine learning algorithms have emerged. For the branch of artificial intelligence - machine vision technology, supervised machine learning is mostly involved, and the labeled data set is the prior experience of supervised machine learning. [0003] The existing video tagging method uses a video tracking algorithm to track objects appearing in the video, and then automatically tags each video frame according to the tracking result. Taking the specific labeling type of object detection as an example, the Lucas-Kanade differential optical flow algorithm is used to calculate the movement of objects in the video to realize vi...
