Classification: CPC G | IPC G

Claim 3:
4. A training data generation method comprising:
clustering, by a processor, a plurality of frame images that constitute first moving image data to generate a plurality of groups, based on a specific image feature value;
randomly selecting, by the processor, from each of the plurality of groups, a first given number of the frame images as second moving image data;
randomly selecting, by the processor from each of the plurality of groups from which the second moving image data was extracted, a second given number of the frame images as third moving image data, the second given number being larger than the first given number;
generating, by the processor, first training data that is labeled data relating to a specific recognition target from the frame images composing the second moving image data;
learning a first training data that is labeled data relating to a specific recognition target, from the first given number of the frame images that constitute the second moving image data; and
generating, by the processor using the first model, second training data that is labeled data relating to the specific recognition target, from the second given number of the frame images that constitute the third moving image data.
