Classification: CPC G  H | IPC G  H

Claim 0:
1. A method of calibrating a broadcast video feed, comprising:
receiving, by a computing system, a target broadcast video feed for a target sporting event;
partitioning, by the computing system, the target broadcast video feed into a plurality of target frames;
for each target frame in the plurality of target frames, generating, by a neural network, a target homography matrix, wherein the neural network is pre-trained, the generating comprising:
generating a playing surface agnostic view of a playing surface in each target frame,
identifying a template that most closely matches the playing surface agnostic view of the playing surface,
retrieving a template homography matrix associated with the template,
predicting a relative homography matrix based on the template and the playing surface agnostic view, and
generating the target homography matrix based on the template homography matrix and the relative homography matrix; and

calibrating, by the computing system, the target broadcast video feed by warping each target frame by a respective target homography matrix.
