Method and apparatus for determining text track in video, and device, and medium

An electronic device, comprising:

• at least one processor;
• and
• a storage apparatus, configured to store at least one program, wherein the at least one program, when executed by the at least one processor, causes the device to:
• determine a first feature set corresponding to a first text set and a second feature set corresponding to a second text set, the first text set being located in a target frame of the video, the second text set being located in a plurality of frames preceding the target frame in the video, and a text in the second text set being associated with a text trajectory in a text trajectory set;
• determine a degree of association set based on the first feature set and the second feature set, a degree of association in the degree of association set indicating a probability of a text in the first text set being on the text trajectory in the text trajectory set;
• and
• determine a text trajectory corresponding to the text in the first text set based on the degree of association set.

A non-transitory computer-readable storage medium, having a computer program stored thereon, wherein the computer program, when executed by a processor, cause the processor to:

• determine a first feature set corresponding to a first text set and a second feature set corresponding to a second text set, the first text set being located in a target frame of the video, the second text set being located in a plurality of frames preceding the target frame in the video, and a text in the second text set being associated with a text trajectory in a text trajectory set;
• determine a degree of association set based on the first feature set and the second feature set, a degree of association in the degree of association set indicating a probability of a text in the first text set being on the text trajectory in the text trajectory set;
• and
• determine a text trajectory corresponding to the text in the first text set based on the degree of association set.
