Maureen Stone of Xerox Palo Alto Research Center will speak on ``Automatically Fitting Splines to Pictures.'' TIME: 3:30 PM ROOM: MC 5158 ABSTRACT For publication quality graphics it is important to have a resolution independent representation for text and illustrations. One way to achieve this is to describe the outline of each shape as a parametric cu- bic curve or spline. Producing such a representation for a complex image, however, can be a tedious task. This talk will describe a method for automatically gen- erating efficient spline approximations from sampled data. Using this algorithm it is possible for a designer to sketch or scan a shape and let the computer define the curves for the outline. February 21, 1984
