Figure 3

An example of ground-truth. The blue boundary boxes represent the ground-truth of the pharyngeal swallowing reflex. The starting point of the swallowing reflex is defined as the first video frame of the head of bolus reaching the lower edge of the mandibular ramus. The end point of the swallowing reflex is defined as the last video frame in which the head of the bolus reaches the vallecular sinus until the first time of hyoid bone elevation is triggered by pharyngeal swallowing.
