【摘要】 方向蛇模型的优点是在模型中不仅运用图像的梯度特性,还充分运用梯度的方向特性,从而提高了图像分割的准确性。文章给出了方向蛇模型的动态规划优化算法,避免模型因采用变分法优化而必须面对的难以达到全局最优,甚至局部最优的现象,提高了图像目标轮廓的检测效率。实验结果表明该方法是有效的。更多还原

【Abstract】 Directional snake can improve the detecting capability by charactering image features not only using gradient but also using the directional information of gradient vector.In this paper,the dynamic programming method to solve the directional snake energy function is proposed,not variational method.So we can avoid the deficient caused by using variation.The experiment result demonstrates the efficiency and effectiveness of our method.更多还原
