Fig.2.
Registration comparison between the Anterior 20 points (top) and the Distributed-8 points (bottom). The anterior surface of the constraining heart surface was oriented to the left and the posterior to the right. The correspondence points used are shown in black (a). Localization error (in millimeters) was mapped onto the registered electrodes (b) with high error in red and low error in blue. Electrodes with localization error below 5 mm were colored blue and with localization error at or above the same threshold were colored red (c). (Color figure online)
