3.2.1.1.3 Experiment Group. The Experiment group has the following settings:
• Average Speed for (s) - this setting specifies the time period or window (in
seconds) over which the average speed is calculated. This setting is used to
minimize jitter in the calculation of average speed. If the setting is left at 0,
the average speed calculations will vary widely (jitter). Thus, the setting
needs to be greater than 0 and less than the amount of time the tracked object
spends in the arena over which the average speed is calculated. Frame rate
also affects the jitter, so if the frame rate is changed, the Average Speed for (s)
would probably need to be changed as well.
Note:
The average speed calcualted for different LEDs attached to the same tracked
animal may not be exactly the same value event though this setting is optimized.
A small amount of jitter may still be present that affects the calculations.
• Animals in Area - this setting specifies whether a single or multiple animals
are being tracked and has dropdown selectable values of Single and Multiple.
This setting does not appear in Object Contour mode since there is only one
animal being tracked.
3.2.1.2 Source Tab(s)
There are one or two Source tabs, each of which contains settings its video
source (either camera or file). If the video source is a camera, the Source tab contains
a Camera group, a DVR group, and a Calibration group of settings. If the
video source is a file, the Source tab contains a File group, a DVR group, and a
Calibration group of settings. The image illustrates the Source tabs in File mode
and Camera mode.
