摘　　要：本文提出了两种由造影图像序列估计冠状动脉运动参数的算法:光流法和动态规划法。采用临床得到的单面冠状动脉造影图像序列对两种算法进行了验证,通过比较其估计结果,分析了它们的优缺点及适用范围。In this paper two approaches for estimating motion of coronary arteries in digital angiotraphic image sequences are proposed. They are based on optical flow method and dynamic programming respectively. The performance of both motion estimation methods are demonstrated on clinical single-plane angiographic image sequences of coronary artery. Results are compared and characteristics are analyzed.
