A computer-implemented method for adjusting stereo images includes receiving a video sequence associated with a recorded setting of a stereoscopic camera, the video sequence comprising pairs of left and right images. The diodes may include a cathode assembly having a cathode electrode, a N+ substrate layer on the cathode electrode, a N buffer layer on the N+ substrate layer, and a N\u2212 bulk layer on the N buffer layer. A digital video camera is disposed within the housing to image the anatomical structure on a display. The first and second switch structures are operable between each of the first, second, third, and fourth positions to alternatively connect each of the plurality of PSUs to one of the first and second input lines and connect, when each of the dual lines is charged, both of the first and second input lines to at least one of the plurality of PSUs.
