  • Publication number: 20110279697
    Abstract: Systems and methods for repeat photography and difference extraction that help users take pictures from the same position and camera angle as earlier photos. The system automatically extracts differences between the photos. Camera poses are estimated and then indicators are rendered to show the desired camera angle, which guide the user to the same camera angle for repeat photography. Using 3D rendering techniques, photos are virtually projected onto a 3D model to adjust them and improve the match between the photos, and the difference between the two photos are detected and highlighted. Highlighting the detected differences helps users to notice the differences.

  • Publication number: 20110282643
    Abstract: A statistical machine translation (SMT) system employs a conditional translation probability conditioned on the source language content. A model parameters optimization engine is configured to optimize values of parameters of the conditional translation probability using a translation pool comprising candidate aligned translations for source language sentences having reference translations. The model parameters optimization engine adds candidate aligned translations to the translation pool by sampling available candidate aligned translations in accordance with the conditional translation probability.

  • Publication number: 20110283087
    Abstract: A first processing unit is implemented by executing a first application program by using an internal computer in an environment where a first operating system is operating. The first processing unit performs a first process or an external service call in accordance with instruction information describing a process to be executed. A second processing unit is implemented by executing a second application program by using the internal computer or an additional computer connected to the internal computer in an environment where a second operating system is operating. The second processing unit performs a second process when instructed by an external service call to execute the second process. When the instruction information includes information specifying the second process as the process to be executed, a transfer unit updates the information included in the instruction information, and transfers the updated instruction information to the first processing unit.
