  • 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.

  • Patent number: 8537824
    Abstract: A method for processing messages in MMS, which includes: after receiving a message from a user side, an MMSC notifying a home Value Added Service Applications Server corresponding to receivers of the message to process the message according to each identifier, which is carried in the message, of the receiver that belongs to the Value Added Service Applications Server and that is carried in the message. A system for processing messages in the MMS is further disclosed. By adopting the technique solution provided in the invention, it could successfully implement the message service of a terminal sending messages to multiple receivers that belong to the same Value Added Service Applications Server. Moreover, it could further reduce the message flux between the MMSC and the Value Added Service Applications server so as to reduce the occupancy of the communication resources, increase the efficiency and save the cost.

  • Publication number: 20090280781
    Abstract: The present invention discloses a message storage method, including: receiving a new message including message contents and service information; checking whether a seed message of the new message is stored, the seed message being a message with identical message contents to the new message; and creating an association relationship between the service information of the new message and the stored seed message, if a seed message of the new message is stored; and storing the received new message, if no seed message of the new message is stored.

  • Publication number: 20070088848
    Abstract: The present invention provides a method that restricts the number of times that a multimedia message can be forwarded among several multimedia messaging service centers (MMSCs). When the originator MMSC forwards a multimedia message to the next MMSC, the MMSC adds a new field: a forward counter, in the message and assigns an initial value to the field. Then, the modified message is sent out to the next MMSC in the MM4 protocol. If the recipient terminal of the message belongs to the current MMSC, the current MMSC simply delivers the message to the recipient in the MM1 protocol and the process is completed. Otherwise, the multimedia message will be forwarded to the next MMSC with the forward counter incremented by one until either the right MMSC receives the message or the forward counter reaches the predefined maximum number. Then MMSC process the message according other rule.
