Fig. 3. Segmentation phase: (a) - potential contour of left and right ventricle (scaled down
image after thresholding with weak distance potential filter), potential contour of left and
right ventricle (original image), (c) - potential contour of right ventricle and expert mask
( M ri,in - white), (d) - potential contour of left ventricle and expert mask ( M le,in -white)
