I am just curious to know if the following code can be used without service but still perform the same. Can you let me know if this is a possibility with the following code?

Hi @michaelsalerno ,
I'm not sure I understand what you mean by "without service", can you elaborate?
Thanks!,
Filip
Dear @filipjeretina ,
Yes, if my laptop did not have any wifi, but I still wanted to use the program the same.
If I was in a remote area without wifi or a way to connect my laptop to the internet.
From Michael Salerno
is this a possibility?
I know when you load it up it says something about converting the blobs via a website? But I want to know if it is possible to have it run offline, no connection to the internet, to maintain consistency. I do not want to have the image recognition be based on the connection, but rather its ability to recognize me.
michaelsalerno I do not want to have the image recognition be based on the connection, but rather its ability to recognize me.
This is not the case even if you have network connection. The blobs (models) are trained to recognize human shapes. They are static and don't change. If the blob you need in the script is downloaded, you can use it without internet connection.
Or am I misunderstanding?
Thanks,
Jaka
Dear @jakaskerl ,
I have tried it on my end, and i get an error stating that it can't connect to the API.
From Michael
What is it using for the segmentation? A yolo model?
I want to see what the code is using, and I want to see what images and know how many images this is trained on.
michaelsalerno
Can you paste this error you are getting?
michaelsalerno What is it using for the segmentation? A yolo model?
The example you linked to is not using segmentation, only detection using a MBnet model. https://docs.openvino.ai/2024/omz_models_model_person_detection_retail_0013.html
Thanks,

How many images is that model trained off of?
michaelsalerno
It's an SDK issue, yes.
Add:
models = getSupportedModels(printModels=False)
try:
zoo_models = blobconverter.zoo_list()
except requests.exceptions.ConnectionError:
zoo_models = []to depthai_sdk\components\nn_component.py line 230
michaelsalerno How many images is that model trained off of?
I don't know, there isn't any info on the website.
Thanks,
Jaka
When connecting to the internet, and using the OPENVINO model, is this technically cloud computing?
michaelsalerno
No, cloud computing means you are running inference on some other machine in the cloud. In the case of depthai, the model is loaded on the OAK device and is running on RVC VPU. This is called edge computing.
Thanks,
Jaka
Thank you, I really appreciate it!
If it is still only working through wifi, does that mean its edge computing still? Or does this mean that it is cloud computing?
michaelsalerno
Just because the OAK device is connected via WiFi does not mean it’s cloud computing. WiFi is simply the medium for network connectivity. If the inference is still happening locally on the OAK device and not on a cloud server, it’s still edge computing.
Cloud computing only applies if the actual computation (inference) is happening on a remote cloud server.
Thanks,
Jaka
Thank you for all your help!
One last question,
What NN is it using? Luxonis published information on latency that I would like to use, and I am curious to know which one it is so I can accurately talk about latency.
