Fig. 7.

Two examples where the voting-based method fails to predict the correct landmark locations, whereas the proposed method still performs well. (a) and (e) are the two images selected from the testing set, along with their manual landmarks 5 and 6; (b) and (f) show the automatically detected landmarks by using the proposed method; (c) and (g) show the detected landmarks by using the voting-based method, with their corresponding voting maps for the two landmarks shown in (d) and (h), respectively, where the white ventricular contours are provided as references for better comparing across images.
