gen_empty_obj — 创建一个空对象元组。
gen_empty_obj( : EmptyObject : : )
算子 gen_empty_obj creates an empty tuple.
This means that the output parameter does not contain any objects.
Thus, the operator count_obj returns 0.
However, clear_obj can be called for the output.
It should be noted that no objects must not be confused
with an empty region. In case of an empty region,
i.e. a region with 0 pixels count_obj returns
the value 1.
