  • Patent number: 11908219
    Abstract: The disclosure provides a method and a device for processing information, an electronic device, and a storage medium, belonging to a field of artificial intelligence including computer vision, deep learning, and natural language processing. In the method, the computing device recognizes multiple text items in the image. The computing device classifies multiple text items into a first set of name text items and a second set of content text items based on semantics of the text items. The computing device performs a matching operation between the first set and the second set based on a layout of the text items in the image, and determines matched name-content text items. The matched name-content text items include a name text item in the first set and a content text item matching the name text item and in the second set. The computing device outputs the matched name-content text items.

  • Publication number: 20220301286
    Abstract: A method and apparatus for identifying a display scene, a method and apparatus for training a model, a device, a storage medium and a computer program product are provided. An implementation of the method may comprise: acquiring a feature vector of a to-be-identified image and acquiring a base library feature vector set; ascertaining, from the base library feature vector set, at least two candidate feature vectors based on a similarity coefficient between the feature vector of the to-be-identified image and each feature vector in the base library feature vector set; performing threshold comparisons on similarity coefficients of the at least two candidate feature vectors, to obtain a target feature vector; and determining a display scene of the to-be-identified image based on a display scene tag corresponding to the target feature vector.

  • Publication number: 20210209395
    Abstract: The disclosure provides a method for recognizing a license plate. The implementation includes: obtaining a feature map including a plurality of feature vectors of a license plate region; sequentially inputting the plurality of feature vectors based on a first order into a first recurrent neural network for encoding to obtain a first code of each of the plurality of feature vectors; sequentially inputting the plurality of feature vectors based on a second order into a second recurrent neural network for encoding to obtain a second code of each of the plurality of feature vectors; generating a plurality of target codes of the plurality of feature vectors based on the first code of each of the plurality of feature vectors and the second code of each of the plurality of feature vectors; and decoding the plurality of target codes to obtain a plurality of characters in the license plate.
