How to avoid zooming in and out all the time?
- My recommended workaround is to use
Scale max
property to limit the zoom.- In the group
Tracking target location
,- Set
Zoom
to large value such as1.0
. - Set
Scale max
to small value such as1.4
-2.0
. This property will control the amount of zoom.
- Set
- In the group
- Another recommendation is setting
Nonlinear band
.- Set larger value (around
0.1
) toNonlinear band (Z)
. - If still this setting keep changing the zoom,
please consider to set
Ki
to0
so that tracking will not use the integration term.
- Set larger value (around
I think this issue should be improved by future improvement.
My current idea for future release is separating Kp
for zoom from that for pan/tilt.
Face detection is not accurate when shot from side
The face detection library in this plugin is trained with frontal faces. Especially if the face is shot from side, the subject is keeping moving her/his face up and down, or having microphone or a facial mask, the size of the detected face becomes vibrating and results zoooming in and out, or sometimes lost the face.
I think this issue should be improved by future improvement. My current ideas are below but I cannot promise when to implement them.
- adding options to choose different face-detection algorithm.
- adding a property to adjust the threshold of face detection algorithm.
