Image processing error measurement in test set. Image processing error measurements in the full test set () as dice similarity coefficient (DSC) and point to curve (P2C) between automatic segmentation and manual delineation.

Dice similarity coefficient (DSC)Point to curve (P2C)

Endocardium overall0.91 ± 0.032.1 ± 0.5 mm
Endocardium ED0.93 ± 0.031.9 ± 0.6 mm
Endocardium ES0.85 ± 0.042.3 ± 0.5 mm
Epicardium overall0.93 ± 0.022.1 ± 0.5 mm
Epicardium ED0.94 ± 0.022.1 ± 0.6 mm
Epicardium ES0.91 ± 0.032.2 ± 0.7 mm

Differences are expressed as mean ± SD. For a perfect overlap between the regions DSC should be 1 and P2C should be 0. ED = end diastole, ES = end systole.
