Abstract
Data points have a direct effect on the shape of B spline curve. In order to get the good result that B spline curve can describe the image edge better, this paper studies an adaptive 3 non uniform B spline curve interpolation algo-rithm. It adjusts point location and the number by using large curvature of the B spline curves in the type value points. Through the error of B spline curve and the image edge, it further optimizes the data points. The B spline curve fits edge. Experimental results show that, the B spline curve can describe the edge better.关键词
