| 摘 要： | 由于交互式分割中Live-wire算法运算速度较慢和操作复杂的问题,该文提出了改进的IS分割算法,在其代价函数中,使用Canny算子代替Laplace算子,并加入了像素边界函数、内边界函数和外边界函数等约束条件,较大的提高了算法运算速度的同时也提高了精度。

| Abstract: | In view of the problems of the precision of segmentation and that the speed of interactive segmentation algorithm is slow,we have made the improvement to original Live-wire algorithm.The improved algorithm uses the canny-operator to replace the laplace-operator,and uses the automatic segmentation algorithm in ITK to segment excess.It can enhance operating sp eed,at the same time,can enhance the precision greatly. |
