进算法既可以有效地检测出一些拐角点和凹点,又可以避免目标边缘收敛于某些噪声点
或伪边缘点,可达到良好的体分割效果.-Use of local image gradient information region, while the use of sequential images of the overall situation between the local area information and its relevance to re-structure the external energy function and in accordance with the ratio of internal and external energy, the right to adjust the value of dynamic parameters. Experimental results show that the improved algorithm not only can be effectively detected in a number of corner points and concave point, and prevent the goal of the edge of convergence in certain noise or pseudo-edge point, the body can achieve good segmentation results.
