An improved post-processing technique is developed to remove MRI artifact arising from rigid translation motion: First,the spectrum shift method is applied to remove phase-encoded direction translation motion.
本文对M R I图像刚性平移运动伪影提出了一个改进的后处理方法:首先用谱平移理论消除频率编码方向平移运动;然后建立模糊模型表示图像的背景并对其进行抑制,用数学形态学的方法确定图像的支撑域;最后以能量熵为收敛准则,用相位恢复算法对频率编码方向残余的子像素移动造成的伪影和相位编码方向的伪影进行消除。
The algorithm needs the manipulator to execute two translation motions and a rotation motion,and requires only two feature points in the scene.
该方法需要机械手平台做两次平移运动和一次旋转运动,只需要场景中两个特征点,所以具有方便性和实用性。
Platform drift motion equation and platform error model on the tossing base are also deduced amply.
