Stralen en koorden

Within each short-axis plane, a closed contour is found by interpolating between the intersection points; for this, the radial coordinate com- ponent r is interpolated over the

initialization around the manually chosen points in the first frame is used as the ROI to be matched. Block matching is applied by computing the cost function for each point in the

From the synthetic data, spatiotemporal sampling errors D of both methods were calculated by sampling a distance function from the beating ellip- soid’s surface and subtracting the

Point-to-point errors for projection of the training shapes on the shape model of the coupled (black) and uncoupled AAM (red) in L-1-O, for models built on an increasing number

The presented method reliably detects the long axis using dynamic programming and a Hough transform for circles, based on detection of the LV center in slices perpendicular to

De gepre- senteerde techniek kan de lange as betrouwbaar vinden met behulp van dynamic programming en een Hough transform voor cirkels, gebaseerd op detectie van het midden van
