MLV: the Myocardium of the left ventricle, LABC: the left atrium blood cavity, LVBC: the left ventricle blood cavity, RABC: the right atrium blood cavity, RVBC: the right ventricle blood cavity, ASA: the ascending aorta, PUA: the pulmonary artery
Average DSC is average of classes that excluded background
