A Combined Random Forests and Active Contour Model Approach for Fully Automatic Segmentation of the Left Atrium in Volumetric MRI

<div>The tissue probability maps estimated from individual CRF and multiconcatenated RFs for a target subject. (a) The axial slice from the original volumetric data. (b)–(d) Voxels with more than 0.6 confidence (green spots) in the outcomes of an individual CRF with iterations 1, 2, and 5, respectively. (e) Fusion of each individual CRF. (f) Ground truth.</div>
