  • Patent number: 8350859
    Abstract: The present invention discloses a method and apparatus for changing lip shape and obtaining a lip animation in a voice-driven animation, and relate to computer technologies. The method for changing lip shape includes: obtaining audio signals and obtaining motion extent proportion of lip shape according to characteristics of the audio signals; obtaining an original lip shape model inputted by a user and generating a motion extent value of the lip shape according to the original lip shape model and the obtained motion extent proportion of the lip shape; generating a lip shape grid model set according to the obtained motion extent value of the lip shape and a preconfigured lip pronunciation model library. The method for changing lip shape in a voice-driven animation includes an obtaining module, a first generating module and a second generating module. The solutions provided by the present invention have a simple algorithm and low cost.

  • Patent number: 8300883
    Abstract: A sketch generating system and a method for generating a sketch based on an image are provided. The system includes: a sketch database and a generating subsystem. The sketch database stores local image samples and corresponding local sketch units in different categories. The generating subsystem extracts geometrical features from an input image, retrieves local image units from the input image according to the geometrical features; as to each local image unit retrieved, searches the sketch database for a local sketch unit corresponding to a local image sample having a largest similarity value with the local image unit, and combines all local sketch units found to form one sketch.

  • Patent number: 7212507
    Abstract: A method of controlling the performance of a radio link between a base transceiver station and a radio terminal for a wireless transmission system is provided. A radio network controller (RNC) monitors a directly observable L-2 parameter, and determines a without explicit L2-L1 signaling a threshold violation by the L-1 parameter for accordingly triggering a status change of the radio link. Namely, a L-2 radio resource management algorithm prompts the radio terminal and the RNC to perform a radio resource management action whenever the L-1 parameter violates a L-1 threshold. Such an action could be directly downgrading or upgrading the transmission rate on the radio link, or a radio link reconfiguration. The L-1 parameter may be the radio block error rate r, and the L-2 parameter may be the PDU retransmission rate R.
