6. If you want to find specific frames where changes occurred in already defined ROIs, use the
Detector
Control
functions, as follows:
Option Description
This button starts a search, from the current frame forward, for any frames in
which significant differences in ROIs (based on the
Minimum Number of
Blocks
selection) are detected. The start time of each detected frame is listed
in the
Start Time
column in window's Detector List.
As each difference frame is detected, the frame image is displayed in the
Video Display
area. The process continues until the end of the time interval is
reached, or until the
Stop
button is clicked.
This button performs the same actions as the
List + Pictures
button, but does
not display the frame images. The process continues until the end of the time
interval is reached, or until the
Stop
button is clicked.
This button can be used to search for each next frame (one frame each time
the button is clicked) in which there is an applicable difference. The frame
image is displayed in the
Video Display
area.
You can view selected frames by clicking their start times in the Detector List. The detected differences in
the frame are indicated by light blue blocks.
You can clear the Detector List by clicking the
button.
7. If you want to find "episodes" (sets of consecutive frames in which a significant difference in ROIs is
detected), do the following:
•
From the
Detect only episode longer than
dropdown list, select the length of time over which
changes must continuously occur.
NOTE:
The default duration is 1.5 seconds. Values from 0.1 seconds to 5.0 seconds can be
selected. In general, the shorter the duration, the more easily episodes will be detected.
