Abstract: An image processing method performed by a computer, the method including: changing a rendering parameter in a three-dimensional model of a recognition target; and generating teacher data of the recognition target based on the rendering parameter changed by the changing. Thereby, sufficient amount of teacher data can be obtained, without any unfavorable redundancy.

Abstract: An information processing apparatus includes a memory; a processor coupled to the memory; and one or more resources, the processor being configured to allow a plurality of the processes to be performed on one of the one or more resources to obtain the exclusion in parallel by optimistic locking control in a first phase, and execute one of the plurality of processes on the resource in a state where the exclusion is obtained by pessimistic locking control in a second phase.

Abstract: An image processing method for an image recognition using teacher data of a recognition target, the method including: designating a mask designation area which is at least a part of a portion other than a specific characteristic portion in an image of the teacher data of the recognition target; and generating masked teacher data by masking the designated mask designation area of the teacher data of the recognition target, so that variety of teacher data can be increased without any unwilling bias or deviation.

Abstract: A processor generates, according to difference information that represents a difference between stationary points in a volume that represents a management unit for a storage area and that is associated with a plurality of generations, aggregate information in which the difference information for the plurality of generations is aggregated. The processor is configured to associate the aggregate information with a state of the volume at an oldest stationary point. The processor is configured to associate update information for a volume that has been updated from a state of the volume at a latest stationary point.
