%X Boundary extraction is the foundation of image recognition.A method of B-spline active contours boundary extraction based on conjugate gradient vector is presented.With human-machine interface,it gives a B-spline curve which is close to and similar to the objective edge in shape and location.Rather than evolving deformable curve with every pixel on the curve in conventional method,the proposed method evolves the curve with controlled node points which are much less than pixel points in numbers,so computatio...
