Name of a Detection Tool object
Detection description
Quality degradation
when the video image received from a video camera loses quality. For example, the detection tool may trigger upon excessive light, loss of focus, lens blocking, or sudden drop in scene illumination. | |
Image noise analysis | The detection triggers when video noise appears on the image For example, the detection tool may trigger upon low bit rate or ripples in the image (snow) |
Scene change analysis |
The detection triggers when the background of the video image |
changes, indicating a change in the position of the video camera |
in space |
A tool that triggers in the presence of video noise.
For instance, triggering may occur upon low bit rate, or ripples on video.
Blurred image analysis | The detection triggers when the blurred contours appear on the image. |
For example, the detection tool may trigger when the image |
is blurry due to a dirty lens. |
