I would like to know, I’m using python, how can I get the mask information of the target object?

Hi,

You first need to set the **enable\_segmentation** parameter to **true** in the ObjectDetectionParamters structure.

Then, the mask is accessible as a Mat in the ObjectData data structure after calling the **retrieve\_objects** function : [https://www.stereolabs.com/docs/api/python/classpyzed\_1\_1sl\_1\_1ObjectData.html#aff25fe6cafaf46730a2b278426aaafbb](https://www.stereolabs.com/docs/api/python/classpyzed_1_1sl_1_1ObjectData.html#aff25fe6cafaf46730a2b278426aaafbb)

I’m using the ZED SDK 4.0 and I’m getting an issue like this: ‘pyzed.sl. CameraInformation’ object has no attribute ‘camera\_resolution’

Hi @NineSeven,

Without the code, it’s difficult to give an exact answer, but I suppose you’re trying to access camera\_resolution through CameraInformation, but it’s an attribute of [InitParameters](https://www.stereolabs.com/docs/api/python/classpyzed_1_1sl_1_1InitParameters.html#a83d09fa560e127b0498b7427658bab5e) so it gives an error.

Please post a complete code sample if you want me to take a deeper look 🙂

I’ve solved the problem I mentioned above, and now I’m having a problem, I’m trying to combine a custom detector and a mask display, how do I do it?

Hi @NineSeven,

The custom detector should output masks, and you can display them with the tool of your choice.  
It was actually discussed in this topic: [Image segmentation using yolov8 with zed 2i python - #2 by JPlou](https://community.stereolabs.com/t/image-segmentation-using-yolov8-with-zed-2i-python/3565/2)

I hope this helps!
