Automatic Detection Flickering

When using Automatic Detection to detect specific objects (faces, license plates,  screens, persons, vehicles), CaseGuard will scan the video frame by frame to detect your footage for those objects.

In some cases, the system will detect your object (which we will call Object-X) in a few frames such as 1, 2, 3, 4, 6,7 but not detect it in other frames, like frame 5.

Because you want your object to be detected in every frame, we created the  Remove Flickering tool, which forces the system to detect your object in the frames where it didn’t appear (i.e., frame 5, in the previous example). 

How to control Remove Flickering?

From the Automatic Detection Popup, under the “Options” section, you will find a field called “Remove Flickering”. By default, it’s set to be 5, which means that if the system detected Object-X between Frame A and Frame B and missed to detect the object in less than 5 frames between A and B, it will force the system to detect the object in those frames.

In every second of a video, there are about 30  frames. If the system detected an object in all 30 frames and missed to detect the object in less than 5 frames, most likely it’s a mistake. The object is probably in all of those frames. Remove flickering will correct that mistake and it will force the system to detect the object there.

We recommend using Remove Flickering if you find that some of the redacted frames you have are significantly different than the frames after them (i.e., your object isn’t completely redacted).
