| 摘 要： | 在临床实践中,数字减影技术是一种无法替代的有效的血管可视化工具,由于能源能量的波动、设备噪声、病人移动、器官蠕动等,通常的数字减影结果常常出现伪影.本文提出了基于小波变换多尺度积的图像配准算法.该算法可以利用小渡多尺度积提取边缘图像和特征点,具有抗噪性强和边缘定位精确等优点.

| Abstract: | In current clinic practice,Digital Subtraction Angiography technique is an unparallel visualization tool for the blood vascular structures.In practice,due to undulation of energy,pigeons of devices,movement of patient,squirm of organisms,artifacts often appear in the results of usual methods of digital subtraction.A new approach for image regis-tration based on wavelet multi-scale product.The proposed approach applies wavelet multi-scale product to extract edge im-age and a number of feature points having a... |
