[Feature Request] UI Indicator for SAM2 models Download Status (Cached State)

[vishnusureshperumbavoor]

What feature or change would you like to see made?

Currently, when users select the Marker Guided Labelmap for AI segmentation, the required ONNX models are downloaded and cached. However, there is no visual feedback in the UI indicating that the model has been cached. This lack of feedback can cause confusion, as users may not know if the tool is ready or still preparing in the background.

Why should we prioritize this feature?

It improves user experience by providing clear feedback about the model's caching status

Yeah, maybe you can help us with that

I'm planning to implement it like this

• Show a download started notification, if the model is not in the cache.
• Show a download completed notification, after the download finishes.
• Do not show any notifications if the model is already in the cache

Let me know if this approach looks good or if you have any suggestions!?

To implement this, we need to export ONNX_EVENTS from cornerstone3d. If the above approach looks good, I will create a PR on cornerstone to add the necessary export. @sedghi

Let's do that first, before we get a design from Dan

I have created the PR. Please check it out @sedghi

@sedghi @dan-rukas Any update on the design part?

It is not a priority for us at the moment
