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.

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.
