Line crossing motion events

[FerielKHA]

My understanding of today's gate report is that objects in motion are detected. These objects are tracked from frame to frame and if the centre of the object bounding box crosses a user defined line, and the object is of a certain size, then a motion event is recorded.

We're interested in the same principle except that we'd like to record the info in each frame as welll as the "event" (which is understood to be the frame most closely corresponding to the moment the object crossed the line).

Our goal is to show a timeline on the player that would highlight all of the motion events and allow the user to click on an event to review it.

A user will want to be able to set the main parameters for the motion detection algorithm.
