中文说明：这是图像分割算法中的一种交互式图像分割方法，livewire算法通过人工选择起始种子点和目标种子点，经过权值计算确定图像边缘，实现人机交互的半自动图像分割。
English Description：
This is an interactive image segmentation method in the image segmentation algorithm. Livewire algorithm realizes the semi-automatic image segmentation of human-computer interaction by manually selecting the starting seed point and the target seed point, and determining the image edge through weight calculation.
