Shape modeling based on specifying the initial B-spline curve and scaled BFGS optimization method

摘要: In this paper, we consider the problem of fitting B-spline curves to a set ordered points, by finding control points and location parameters. The presented method takes two main steps: specifying initial curve optimization. determines number position such that is very close target curve. proposed introduces length parameter in which allows us adjust increases precision Afterwards, scaled BFGS algorithm used optimize foot simultaneously generates final Furthermore, present new procedure insert point repeat optimization method, if it necessary modify accuracy generated Associated examples are also offered show approach performs accurately for complex shapes with large data able generate precise high degree approximation.
