  • Publication number: 20230293111
    Abstract: An information processing apparatus includes a first acquisition unit, a separation unit, a first identification unit, and a second identification unit. The first acquisition unit is configured to acquire measurement data being time-series data obtained by measuring a biological signal by a measurement apparatus. The separation unit is configured to separate the measurement data acquired by the first acquisition unit into a plurality of signal components by a multivariate analysis. The first identification unit is configured to identify, from among the plurality of signal components, a signal component including an unwanted component other than a biological signal being a measurement target. The second identification unit is configured to identify, using, as reference data, the signal component identified as including the unwanted component by the first identification unit, a signal component including an unwanted component again from among the plurality of signal components.

  • Publication number: 20190285397
    Abstract: A measuring apparatus, a measuring system, a measuring method, and a computer-readable non-transitory recording medium storing program code. The measuring apparatus and the measuring method include obtaining data indicating position coordinates of a surface of an object, and outputting information to associate amount information of the data belonging to at least one of a plurality of subspaces obtained by dividing a coordinate space with the plurality of subspaces when the amount information and the plurality of subspaces are displayed. The measuring system includes a measuring device and the measuring apparatus. The recording medium stores the program code for causing a computer to execute the measuring method.
