How can I check the predictions? I don't quite understand why the predictions is a 16 x 5 matrix. I presume 16 means the 16 joints but what about the 5?

[anewell]

The five values include: the x, y coordinates transformed to the original image space, the x, y values in the heatmap coordinate frame, and then the score of the detection. There is an additional flag to save the heatmaps if you want them "-saveHeatmaps", but to load predictions without them you should call loadPreds without the true flag for that second argument.
