  • Patent number: 10733416
    Abstract: A processor of an information processing device acquires an image, determines base point from the image, and acquires first position information of the base point. The processor determines a reference direction indicating characteristics of color information of a section of the image around the base point. The processor acquires a sample for each of a plurality of reference points acquired sequentially in accordance with a predetermined condition from a starting point determined on the basis of the base point and the reference direction. The processor calculates as frequency information, frequency components of changes in the color information with respect to the second position information for the plurality of samples, using a linear prediction coefficient calculated using a Yule-Walker method without applying a window function. The processor causes the memory to store information associating the frequency information, the first position information and the reference direction, as collation information.

  • Patent number: 10430629
    Abstract: A computer-readable medium and an information processing device are provided that are capable of generating collation information that is unlikely to be affected by acquisition conditions of biometric information. An image is acquired (S1), and a base point is determined from the image (S2). Sample information indicating a change in color information of a surrounding area of the base point is acquired (S3). The sample information is information that associates a plurality of samples with center information corresponding to positions on the image of first reference points. The sample is information that associates color information of second reference points with position information of the second reference points. Based on the acquired sample information, frequency information is generated (S4). The frequency information associates the center information with a frequency component of a change in the color information with respect to the position information calculated for each of the first reference points.

  • Publication number: 20180107961
    Abstract: In a supply chain, an optimal task logic is automatically presented in accordance with a status change occurring in each enterprise in a short time. A task support system generates scenario information of a simulation and generates task logic combining information by combining the scenario information and the task logic of each enterprise. Then, KPI information for each task logic in a scenario is calculated by performing a simulation based on the task logic combining information. Next, status change information relating to a task is read, and a search for a scenario closest thereto is performed. Then, a scenario closest to the status change information is referred to, a KPI relating to the scenario from the KPI information is acquired, a scenario achieving the input importance KPI most is acquired, and a task logic that is combined with the scenario in the task logic combining information is calculated as an optimal task logic.
