![]() ![]() If it is in a masked area, it is assumed to be a false positive. The bottom center of the detected object's bounding box is evaluated against the mask. These should be used to filter any areas where it is not possible for an object of that type to be. Object filter masks: Object filter masks are used to filter out false positives for a given object type based on location. To see this effect, create a mask, and then watch the video feed with Motion Boxes enabled again. Over masking will make it more difficult for objects to be tracked. Motion is also used during object tracking to refine the object detection area in the next frame. ![]() Keep in mind that this mask only prevents motion from being detected and does not prevent objects from being detected if object detection was started due to motion in unmasked areas. ![]() For example, you want to mask out your timestamp, the sky, rooftops, etc. Try watching the debug feed with Motion Boxes enabled to see what may be regularly detected as motion. Motion masks: Motion masks are used to prevent unwanted types of motion from triggering detection. ![]()
