System and method for player reidentification in broadcast video

A system for re-identifying players in a broadcast video feed, comprising:

• a processor;
• and
• a memory having programming instructions stored thereon, which, when executed by the processor, performs one or more operations, comprising:
• retrieving a broadcast video feed for a sporting event, the broadcast video feed comprising a plurality of video frames;
• generating a plurality of tracks based on the plurality of video frames, wherein each track comprises a plurality of image patches associated with at least one player, each image patch of the plurality of image patches being a subset of a corresponding frame of the plurality of video frames;
• for each track, generating a gallery of image patches wherein a jersey number of each player is visible in each image patch of the gallery;
• matching, via a convolutional autoencoder, tracks across galleries;
• measuring, via a neural network, a similarity score for each matched track;
• and
• associating two tracks based on the measured similarity.

A non-transitory computer readable medium including one or more sequences of instructions that, when executed by one or more processors, perform operations comprising:

• retrieving, by a computing system, a broadcast video feed for a sporting event, the broadcast video feed comprising a plurality of video frames;
• generating, by the computing system, a plurality of tracks based on the plurality of video frames, wherein each track comprises a plurality of image patches associated with at least one player, each image patch of the plurality of image patches being a subset of a corresponding frame of the plurality of video frames;
• for each track, generating, by the computing system, a gallery of image patches wherein a jersey number of each player is visible in each image patch of the gallery;
• matching, by the computing system via a convolutional autoencoder, tracks across galleries;
• measuring, by the computing system via a neural network, a similarity score for each matched track;
• and
• associating, by the computing system, two tracks based on the measured similarity.
