2.11.3 Offline Functionality
Most offline functionality is only marginally different from its online equivalent.
The major exception is that the optional tracking and behavior functionality
against a recorded file will be slightly different than that against live video. This
is because the compression techniques used to create AVI files of manageable
size inherently discard some of the data that was present in the original, i.e. they
are “lossy” compression techniques. In particular, some color, details, and brightness
information is compromised. Normally the differences are not visible to the
naked eye, but they will cause slight differences in the sensitive algorithms used
for tracking and behavior analysis.
Sending tracking data to the MAP Sort Client is not enabled and does not occur in
offline mode because there are no camera triggers and no neural data to synchronize
with. In addition, Sort Client may not even be installed on the computer
where the offline analysis is being done.
Differences in the user interface are described below:
• Global Config Pane - The frame rate shown is that of the source files
selected. Other sections are unchanged.
• Source Pane(s) - Most Camera adjustments are replaced with a file selection
browsing tool. In their places are simple adjustments for brightness and contrast.
Other sections are unchanged.
• Messages Pane - No differences.
• Tracking Panes (if tracking option is available) - No differences.
• Areas Pane(s) (if tracking option is available) - No differences.
