基于动态规划的序列图像自动分割

DP-Based Automatic Contour Detection for Image Sequences

序列图像在计算机辅助手术和放射治疗的三维重建中起着重要的作用，它要求在可行的计算代价下，实现图像序列的最优化自动边缘跟踪本文提出基于动态规划的最优化方法。

Sequential images play a significant role in reconstruction of 3D images for computeraided surgery and radio-therapy. The most important problem we must solve is to realize optimal and automatic boundary detection with feasible computational coat. In this paper, we develop a dynamic programing(DP)-based method with the aid of 'band' and introduces a novel searching strategy to achivethis goal. Experimenal results in ultrasonic image sequences of normal and abnormal cardiac vessels prove this method to be practicable.
