Background:

Accurate prostate segmentation is crucial for medical imaging analysis and treatment planning.
Existing segmentation methods often require manual intervention or lack comprehensive feature integration.

Purpose of the Study:

To introduce a fully automated method for prostate segmentation.
To improve segmentation accuracy by leveraging both image and contextual information.

Main Methods:

Automated selection of a volume of interest (VOI) using supervoxel segmentation.
Classification of VOIs using random forests (RFs) with image and context features.
Optimization of a Markov random field cost function, incorporating semantic information, via graph cuts.

Main Results:

The proposed method achieved high segmentation accuracy, validated by the Dice metric (DM) on both training and test sets.
Experimental results demonstrated that incorporating context and semantic information significantly improved segmentation accuracy compared to other methods.

Conclusions:

The developed automated method provides accurate prostate segmentation.
The integration of context and semantic information is key to enhancing segmentation performance in medical imaging.
