  • Patent number: 11928790
    Abstract: An object included in a low-resolution image can be recognized with a high degree of precision. An acquisition unit acquires, from a query image, an increased-resolution image, which is acquired by increasing the resolution of the query image, by performing pre-learned acquisition processing for increasing the resolution of an image. A feature extraction unit, using the increased-resolution image as input, extracts a feature vector of the increased-resolution image by performing pre-learned extraction processing for extracting a feature vector of an image. A recognition unit recognizes an object captured on the increased-resolution image on the basis of the feature vector of the increased-resolution image and outputs the recognized object as the object captured on the query image.

  • Patent number: 11281644
    Abstract: In some examples, a first node is able to communicate with one or more second nodes for participating in a consensus system. The first node may receive a plurality of pieces of sequential data from a plurality of data sources. The first node may generate a block for a first blockchain that includes a plurality of the pieces of sequential data in the block. Based at least partially on determining that the data source of the last piece of sequential data entered in the block for the first blockchain is different from a data source of the next piece of the sequential data, the first node may generate a block for a second blockchain that includes the next piece of the sequential data, and may further associate an indicator with the block generated for the second blockchain that indicates the block in the first blockchain.

  • Publication number: 20040138974
    Abstract: If money is paid in from a customer, an outstanding amount of a real account of the customer in each of financial institutions is identified, to calculate a shortage between the outstanding amount and a predetermined amount. Whether the money amount paid in from the customer exceeds the shortage is decided and, if the pay-in money amount does not exceed the shortage, the pay-in money amount is determined to be a pay-in money amount for the real account, to perform pay-in processing. If the pay-in money amount exceeds the shortage, the shortage is determined to be a pay-in money amount for the real account. Then, almost the same arithmetic operations are repeated on real accounts other than the real account for which the pay-in money amount has been determined, to determine a pay-in money amount for the real accounts other than that real account, thus performing pay-in processing.
