  • Patent number: 11954591
    Abstract: This application provides a method of generating a description for a picture set performed at a computer device, and a storage medium. The method includes: acquiring a picture set to be processed; performing picture feature extraction on each picture in the picture set to acquire a picture feature corresponding to the picture, and forming a picture feature sequence corresponding to the picture set by using the picture features corresponding to the pictures; performing scene feature extraction on a picture feature sub-sequence corresponding to each scene in the picture feature sequence to acquire a scene feature corresponding to the scene, and forming a scene feature sequence corresponding to the picture set by using the scene features corresponding to the scenes; and generating textual description information of the picture set according to the picture feature sequence and the scene feature sequence that correspond to the picture set.

  • Patent number: 11934454
    Abstract: Provided are a video retrieval method and apparatus, a medium, and a server. The video retrieval method includes: receiving a video retrieval request from a terminal, the video retrieval request carrying retrieval key information; searching a video database for a natural sentence matching the retrieval key information, the video database including a plurality of videos, each video having a natural sentence obtained through processing frames of the video using an encoder, a decoder and a reconstructor of a neural network; obtaining a video corresponding to the natural sentence matching the retrieval key information; and returning the matching video to the requesting terminal.

  • Patent number: 11868738
    Abstract: The present disclosure describes methods, devices, and storage medium for generating a natural language description for a media object. The method includes respectively processing, by a device, a media object by using a plurality of natural language description models to obtain a plurality of first feature vectors corresponding to a plurality of feature types. The device includes a memory storing instructions and a processor in communication with the memory. The method also includes fusing, by the device, the plurality of first feature to obtain a second feature vector; and generating, by the device, a natural language description for the media object according to the second feature vector, the natural language description being used for expressing the media object in natural language. The present disclosure resolves the technical problem that natural language description generated for a media object can only give an insufficiently accurate description of the media object.

  • Patent number: 11368705
    Abstract: Provided are a video processing method and apparatus, a video retrieval method and apparatus, a medium, and a server. The video processing method includes: performing encoding and decoding on an original video by using the encoder and the decoder, to obtain a video feature of the original video and a hidden state of the original video at a decoding stage; reconstructing a video feature of a target video by using the reconstructor according to the hidden state of the original video at the decoding stage; obtaining a difference between the video feature of the target video and the video feature of the original video; and adjusting a processing parameter of at least one of the decoder and the reconstructor to reduce the difference between the video feature of the target video and the video feature of the original video.
