Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0037] For a sequence of video frames x_t(t=0,1,...,T), when the annotation information is set for one of the video frames in advance, the process of setting annotation information for other video frames in the sequence of video frames according to the annotation information is the video Label information dissemination. For example, set the annotation information y_0 for the 0th video frame x_0 in the video frame sequence in advance, and calculate the annotation information y_1 of the 1st video frame sequentially according to the annotation information y_0, and the annotation information y_2 of the 2nd video frame until the Tth frame of video Frame annotation information y_T, this process is video annotation information propagati...

Abstract

The invention discloses a video frame information labeling method and device, equipment and a storage medium. The method comprises the steps of obtaining a to-be-processed video; for a target video frame in the to-be-processed video, performing feature extraction on the target video frame to obtain a target image feature of the target video frame; according to the image feature matching degree ofthe target video frame and the marked video frame in the to-be-processed video, obtaining a to-be-processed video, determining a guide video frame of the target video frame from the labeled video frames, the guide video frame being used for guiding the target video frame to perform information labeling, and the image feature matching degree being a matching degree between the target image featureand an image feature corresponding to the labeled video frame; and generating target annotation information corresponding to the target video frame according to the annotation information corresponding to the guide video frame. According to the embodiment of the invention, by improving the selection quality of the guide video frame, the accuracy of the generated annotation information is improved.Propagation errors of the annotation information cannot be accumulated, so that the propagation quality of the annotation information is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of video information dissemination, and in particular to a video frame information labeling method, device, device, and storage medium. Background technique [0002] Video annotation information dissemination is an important technology in the field of video processing. It is often used to perform tasks such as video object tracking and grayscale video coloring. [0003] In related technologies, a method based on deep learning is usually used to model the pixel relationship between video frames based on a convolutional neural network, so that the annotation information between video frames is propagated through the relationship between pixels. When using the above method, the convolutional neural network is usually used to model the adjacent video frames. Correspondingly, when using the constructed model for labeling information propagation, the previous video frame of the current video fram...
