Based on the deformation model image segmentation method usually can be divided into parametric deformable models and geometric deformable models two kinds,a LBF algorithm based on region-based active contour model was presented.Aiming at overcoming the difficulties caused by intensity inhomogeneities,LBF introduce a Gaussian kernel function to define a local binary fitting energy,so that local intensity information could be embedded into a region-based active contour model.Through theory analysis and simulation examples about these algorithms,experimental results show that the LBF algorithm improves stability and accuracy of the image segmentation,which has high practical value and broad application prospect.
