Ventricle Boundary in CT: Partial Volume Effect and Local Thresholds
Figure 3
Ventricle extraction: (a) original ventricles in CT, (b) the contour of the GT marked, (c) the result of the thresholding, (d) result of smoothing using snake, and (e) the contour (grey line) of ventricle received by algorithm overlapped over the GT (white area).
