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.

• 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 244.

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.
