Mask Detection
- Can someone be recognized if the actual occlusion value is greater than the configured maximum occlusion value?
- If a person registers with a mask, will that have a significant negative impact on recognition when the person isn't wearing a mask?
- Does SAFR recognize subjects inside a vehicle?
- Can mask detection work without occlusion detection being enabled?
- Does an observed face need to be below the maximum occlusion for the duration of the "Min Stranger Event Duration" setting before an event is triggered?
- If "Learn occluded faces" is checked, will SAFR learn occluded face only if the actual occlusion is less than the configured maximum occlusion?
- Can mask detection occur when occlusion is set to 0?
- When max occlusion is set to 1, occlusion is no longer being reported; only masks are. Is this expected?
- What is the expected behavior when both “Include Stranger Events” and “Only if occluded” are checked?
- How accurate is SAFR’s face recognition for subjects with masks?
