摘要: A method for extracting a smooth polygonal contour from digitized image is illustrated. The ordered sequence of points and the connection graph are first obtained by modified Ledley algorithm in one scan. minimal perimeter polygon subjected to specified constraints then chosen as approximating contour. determination can be reduced nonlinear programming problem, solved an which takes into account weak bonds between variables. Some examples presented, corresponding computing times listed.
