Structure

The entire processing pipeline for the VESSEL12 data is set up in the config.py file.

• Dictionary learning (Unsupervised step). First the dictionary has to be learned on a number of given volumes. The volumes don't have to be annotated.
• Classifier learning (Supervised step). Based on the learned features, train the classifier of choice.
• Testing module. Apply filters from the dictionary and use a classifier.
• Some additional functionality: 3d patch extraction, 3d Gaussian pyramids, loading/saving data. The dictionaries and classifier weights are serialized in the ./Data/Serialized directory.

Preprocessing

IRCAD 20 liver transformed to the above structure

LearnDictionary

Execute the scripts in following order:

1. ExtractPatches.py
   
2. LearnDictionary.py
   

LearnClassifier

Execute the scripts in following order:

1. ExtractXy_multithread.py
   
2. ConcatenateXy.py
   
3. TrainClassifier.py or MakeMeasurements.py
   

Usage

Once the dictionary and classifier are learned, they can by uses on a given volume.
