  • Patent number: 11893767
    Abstract: A text recognition method and apparatus disclosed. The text recognition method includes: obtaining a to-be-detected image; determining a target text detection area in the to-be-detected image, where the target text detection area includes target text in the to-be-detected image, and the target text detection area is a polygonal area including m vertex pairs, m being a positive integer greater than 2; correcting the polygonal area to m?1 rectangular areas to obtain a corrected target text detection area; and performing text recognition on the corrected target text detection area to determine the target text, and outputting the target text.

  • Publication number: 20220301328
    Abstract: A text recognition method and apparatus that relate to the field of information processing technologies are provided. This effectively resolves a low recognition rate of curved text. The text recognition method includes: obtaining a to-be-detected image; determining a target text detection area in the to-be-detected image, where the target text detection area includes target text in the to-be-detected image, and the target text detection area is a polygonal area including m (m is a positive integer greater than 2) vertex pairs; correcting the polygonal area to m?1 rectangular areas to obtain a corrected target text detection area; and performing text recognition on the corrected target text detection area, and outputting the target text.

  • Patent number: 9432250
    Abstract: Disclosed is a method of implementing a redundant network. Ring network nodes in an initial state are set as master stations, ring ports are set in a half-blocked state, a master station election notification message is broadcast to the ring ports within a preset time interval, the nodes receive the master station election notification message, a node quality comparison vector is compared with node quality comparison vectors of the nodes to elect a master and standby stations, one of the ring ports is in the half-blocked state, the other ring ports are in a forwarding state, the master station broadcasts the master station election notification message to the ring ports, the standby master station stops sending the master station election notification message, the ring ports are in the forwarding state, and the message sent by the master station is received.

  • Patent number: 9363206
    Abstract: Provided are a transparent clock passive port election method and device based on the PTP protocol. In the method, by extracting the TLV field of a received announce message, a first port of a network device acquires the clock identification information, forwarding times information and port identification information carried in the TLV field, and then compares the forwarding times information and clock identification information carried in the TLV field to the forwarding times information carried in the TLV field contained in a received announce message from a port by itself, and its own clock identification information, so as to select a port as a passive port.
