This paper proposes an improved model of contour evolution LBF energy function, which combines the CV model energy term to accelerate evolution rate, and combines local mean LBF model information while introducing a global image of the local variance and variance information. Experimental results show that this method can provide accurate smooth closed boundary,and that precision can reach sub-pixel level,and that the recognition accuracy rate is high.
