> Questions about evaluation of disappeared object

Hi there,

If one object doesn't appear in a frame, the groundtruth mask of this this object is "blank". It requires the model output should be "blank" for this object too.
Thus, the intersection and the union are both zero. How does the evaluation function tackle 0/0 issue?
When I look at my results details, under such scenario, it says the score of this frame is 0, but I think it should be 1, right?

Is anyone there could answer my question? Thanks in advance.
