The track box get big width at image bottom when the moment target appear #456
Description
As the target moves upward from the image bottom, the tracking box width gradually expands until the target is fully visible, then returns to its normal size. As the target moves downward from the lower boundary, the tracking box width gradually decreases from the moment the target enters the lower boundary. Could you tell me how to solve it?

ByteTrack KF status is [cx, cy, a, h, vx, vy, va, vh], and width=a*h.
When the front of the car appears from the bottom of the screen, the initial shape is short and wide (that is, the aspect ratio a is very large).
If the initial value of the standard deviation of va is set very small, it is difficult to quickly change the aspect ratio.
The relevant parameter is in the stdArray within the Activate function of STrack.
