incremental_watershed

Implementation of incremental watershed algorithm in C++.

Compilation

To compile you will need openCV availibale on your systeme.

Usage on 3D

The file bench_iws.cpp is a good example of how you can use this repo.

First you need to build a volume manager and set 2 parameter :

• thrashold_ which is MIN_BREADTH in the paper
• And the number of threads

  auto volume_manager = new volumeManager();
  volume_manager->threshold_ = threshold_param;
  volume_manager->nb_threads_ = num_threads;

Then load the volume in memory (check in data_3D folder to see the format used). Then create the graph and then the hierarchie.

  volume_manager->loadVolume(path_volume);
  volume_manager->createGraph();
  volume_manager->buildHierarchy();

To add or remove marker you need to give the program a array where there is the marker's 1D coordinates

volume_manager->addMarkers(markers_object_batched[i]);
volume_manager->removeMarkers(markers_object_batched[i]);

To reset the hierarchy and the MST use : volume_manager->resetPostprocessStructure();
