| 摘 要： | 提出了一种改进的Live Wire交互式图像分割算法。与原Live Wire算法相比 ,改进算法在不增加算法复杂度的同时 ,大大提高了图像分割的性能 ,而且在 3个方面弥补了原算法的不足 :(1)对噪声相当敏感 ;(2 )不能有效地区分图像中的强弱边缘 ;(3)不适用于边缘弯曲程度较大的图像。将改进算法与窗宽 /窗位调整算法相结合用于医学图像分割中 ,取得了良好的分割效果

| Abstract: | An improved live-wire algorithm for interactive image segmentation is presented. In comparison with the existing live-wire algorithm, the proposed one, with the same complexity, greatly improves the performance of image segmentation. Meanwhile, the modified algorithm overcomes the following drawbacks of the traditional one: (1) rather sensitive to noise; (2) inefficient to distinguish between strong and weak edges; (3) inapplicable to segmenting the images with sharp edges. In addition,slide window processing is incorporated in this algorithm, which brings about a better performance in medical image segmentation. |
