Use the
Episode Control
functions, as follows:
Option Description
This button starts a search for episodes, from the current frame forward.
The methodology by which the episode start and end frames are
determined is described in the
How Episodes are Determined
section,
page 219.
The start time and duration of each episode is listed in the
Start Time
and
Duration
columns in the window's Detector List. As each episode is
detected, its first 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 can be used to search for each next episode (one episode
each time the button is clicked).
You can run the frames of an episode by clicking on its entry in the Detector List. Light blue blocks
indicate the detected differences in the frame.
You can clear the Detector List by clicking the
button.
Defining ROIs
When the
Museum Search
window is opened, blue-colored grid blocks cover the entire frame in the
Video
Display
area, indicating that the change detection mechanism currently applies to the entire frame area.
You can focus the change detection mechanism on security-sensitive objects in the frame space by using the
window functions to vary the coverage of the colored grid blocks. (Only the segments covered by colored grid
blocks are considered for change detection purposes.)
For example, you can focus on windows or doors (as shown in the
picture opposite) to monitor opening/closing events.
The following options are provided:
Option Description
This button clears all the current colored grid blocks in the view. You can then use
the
Pencil
tool to define grid blocks for specific ROIs within the view surface.
NOTE:
Change detection does not function unless ROIs are identified by
colored grid blocks.
This button marks colored grid blocks over the entire window surface, meaning that
change detection will apply to the entire camera view. You can then use the
Eraser
tool to remove specific grid blocks.
