solidity_rag_merge.py

What is this?

../../../../_images/solidity_rag_merge1.png

(red region in top image is segmented using euclidean clustering, yellow, purple and red region is segmented by solidity_rag_merge.)

Segment image region which has high solidity, using RAG. It firstly segments image with SLIC Superpixels, generates RAG based on solidity, and then merges regions.

Subscribing Topic

    Raw image. In most cases, this is mask or depth image.

  • ~input/mask (sensor_msgs/Image)

    Region where the label should be ignored.

Publishing Topic

Default Topics

  • ~output (sensor_msgs/Image, encoding: 32SC1)

    Label image of region with high solidity.

Optional Topics

Following topics are published when ~debug is True, see Parameters for more detail.

  • ~debug/slic (sensor_msgs/Image, encoding: 32SC1)

    Label image segmented with SLIC Superpixels.

  • ~debug/rag (sensor_msgs/Image)

    RAG overlayed image.

  • ~debug/label_viz (sensor_msgs/Image)

    Label color overlayed image. This function can be replaced by label_image_decomposer.py but I added for easy debugging.

Parameters

  • ~approximate_sync (Bool, default: False)

    Whether to use approximate for input topics.

  • ~debug (Bool, default: True)

    Debug mode. In this mode, the node publishes ~debug/* topics.
