Table 4 Detection frequency and average frame gaps for a single pen from use case scenario 1. During the ten-hour observation period the majority of the animal IDs have been detected. IDs 44 and 48 (marked with *) were undetected in one video, which led to a considerable increase in the average frame gap.
