AI support for ROItool (nnInteractive)

This tool uses a remote neural network server to assist manual segmentation tasks.

1. Server Setup

The segmentation server must be running, typically on a machine with a GPU.
First, navigate to the src/python/segmentation_server directory and launch the setup.sh script (requires internet access):


cd src/python/segmentation_server ./setup.sh

This will create a Python virtual environment and install the necessary dependencies.

Next, start the server from a computing node using:
src/python/segmentation_server/start.sh

2. Client Configuration

Once the server is running, it will log its IP address and port.
You must update this client's configuration to point to that address.

Edit the file: conf/segmentationserver.conf

Set the REMOTE_SEGMENTATION_BASE_URL to the server's address, for example:


{ "REMOTE_SEGMENTATION_BASE_URL": "http://<SERVER_IP>:1528" }

You must restart Nora for the changes to take effect.

3. Usage

  • Refine ROI (Shortcut: W):
    Select an ROI for drawing and press W to automatically refine its shape based on the underlying image.

  • Refine with Scribbles (Shortcut: Q):
    Select an ROI, draw scribbles to correct it, and press Q to apply the changes.
