For this kind of model, we can directly use its output as final result
just like ssd model. The difference is that it splits output into two
tensors. [x_min, y_min, x_max, y_max, confidence] and [lable_id].
Model example refer to:
From: Wenbin Chen
Add dynamic outputs support. Some models don't have fixed output size.
Its size changes according to result. Now openvino can run these kinds of
models.

These functions encode a slice of alpha (1 to 8 macroblocks) which are
