Hansen, Charles D. | CAD-based computer vision: the automatic generation of recognition stragtegies | Three-dimensional model-based computer vision uses geometric models of objects and sensed data to recognize objects in a scene. Likewise, Computer Aided Design (CAD) systems are used to interactively generate three-dimensional models during these fields. Recently, the unification of CAD and vision s... | 1988 | |

Horch, Kenneth W. | Identification of single units in multi-unit recordings from peripheral nerves | We are developing a computer-based method for identifying individual action potentials in multi-unit peripheral nerve recordings. Threshold level, sinusoidal stimuli are used to elicit phase-locked activity from single units. These action potentials are digitized, and a template is constructed usin... | Peripheral nerve; Neural recordings; Cutaneous mechanoreceptors | 1988 |

Mueller, Timothy I. | Refinement estimation of B-spline curves and surfaces | An algorithm for refinement estimation for B-spline curves is presented. The algorithm uses approximations to the curvature and arc length to decide how a curve should be refined. The algorithm can also be used to produce isoparametric curves or polygonal tessellations from a Bspline surface. | B-spline; Curves; Surfaces; Algorithm; Curvature; Arc length; Isoparametric curves; Polygonal tessellations | 1988 |
