  • Publication number: 20230219226
    Abstract: An indicator related to work performed through a plurality of hierarchical processes is predicted efficiently with high accuracy. The information processing device stores sample data in association with each parameter representing work, the sample data including an indicator generated by execution of lower-level simulation based on a lower-level model set for a lower-level process, and the information processing device predicts an indicator related to predicted work by performing higher-level simulation using the sample data associated with a parameter similar to a parameter representing the predicted work, the higher-level simulation being based on a higher-level model which is set for a higher-level process. If sample data associated with a parameter similar to the parameter representing the predicted work is not stored, the information processing device complements sample data by performing lower-level simulation and performs higher-level simulation using the complemented sample data.

  • Patent number: 8401278
    Abstract: Image retargeting is appropriately performed on stereo pair images composed of at least two images such as in three-dimensional displays. A path of connected pixels in first image data is calculated based on pixel gradient energy. Each pixel in second image data corresponding to each pixel in connected pixels in the first image data is calculated as an initial search point, based on the stereo correspondence relationship between the first image data and the second image data. Pixels that minimize energy between pixels of the first image data and pixels of the second image data in the proximity of the initial search point is calculated as a path of connected pixels in the second image data. A path of optimal connected pixels in the first image data is calculated using the energy.
