I am trying to understand parts of the model and associated paper, and I'm a little confused on the heatmap. The paper makes it seem like it is a Gaussian heatmap with real values. However, based on the variant focal loss and parts of the code, I'm now confused. Are the ground truth heatmaps binary, based on some determined radius from the corner points? And why use a binary approach as apposed to fixed numbers?
