Method of Boundary Detection Based on B-spline Curve Fitting
In order to enhance the tracking accuracy and efficiency of the target area in vision navigation,this paper presents a new kind of boundary extraction n algorithm.It begins preprocessing the acquisition image to get binary image,then fills binary image area based on mathematical morphology to binary image and extracts boundary with classical algorithms,fuses many boundary information into a border area,finally applied non-uniform rational B-spline interpolation method to fit curve.The presented results indicate that this algorithm can correct extract arbitrary complicated shape boundary fast,which definitely provides a better basis for the following image processing.
