Abstract: A training data generation method generate labeled training data used for training an object identification model that is based on machine learning. The training data generation method includes: (A) detecting a moving object in a sequence of images; (B) tracking a same moving object in the sequence of images by using a tracker, to automatically obtain a track that is information representing a time series of the same moving object in the sequence of images; and (C) generating the labeled training data by giving the track as a label to the sequence of images.

Abstract: A model training method trains an object identification model that is based on machine learning. The model training method includes acquiring labeled training data where a track is given as a label to a sequence of images. The track is information representing a time series of a same moving object in the sequence of images and is automatically obtained by a tracker that tracks the same moving object in the sequence of images. The model training method further includes training the object identification model based on the labeled training data.
