  • Patent number: 11727579
    Abstract: An information processing apparatus determines a direction (first direction (12)) from a sensor (10) toward a moving object (20) by detecting the moving object (20) using the sensor (10). The information processing apparatus causes a camera (30) to perform imaging while moving the optical axis direction (34) of the camera (30) along the first direction (12). As a result, a plurality of captured images (32), each of which is captured in the different direction, are generated by the camera (30). The information processing apparatus (2000) detects the moving object (20) by performing image analysis on the captured image (32).

  • Publication number: 20230252765
    Abstract: In a data augmentation device, a data acquisition means acquires two sets of source domain data of a predetermined class from a data group of a source domain, and acquires one set of target domain data of the predetermined class from a data group of a target domain data. An estimation means estimates a structure of a manifold representing a data distribution of the source domain by using two sets of source domain data. A data generation means generates new data of the target domain by using the one set of target domain data and the structure of the manifold.
