This research focuses on defining the strike zone using how the body is in a two-dimensional plane, similar to tasks where objects are identified in pictures. Just like the object detection task, we have decided to use Intersection over Union (IoU) as the metric to evaluate our research.
IoU's calculation involves two parameters: the first is the ground truth, which is manually annotated in the dataset. The second is the target range derived from the algorithm used in the experiment. IoU is computed by measuring the overlap between these target ranges and ground truth, then dividing it by the union to obtain the IoU value. This equation is how we calculate the IoU metric, so we estimate the area of overlap and divide it by the area of union. This metric reflects the correlation between the ground truth and predictions. This research also tested the accuracy of the electronic strike zone used nowadays. I will show you the results of these two metrics and compare them to see which one is more accurate.
