Hi,

Hope you are all well !

I was wondering if SoTu is able to make these 2 points:

Detection of multiple occurrences of the same picture

For example, based on find-object, being able to detect multiple occurences of the same object.

Many objects detection

Another example, still based on find-object](https://github.com/introlab/find-object), to detect many objects in a scene.

Thanks in advance for your insights and inputs on these topics.

Cheers,
X

多次flask extract的话，旧的就被新的覆盖了？可以累加起来吗？
