基于数学方法的不完全投影数据估计

主要对不完全投影图像恢复问题中不完全投影数据进行了研究.对于投影数据不完全时,运用线性插值法和样条插值法在角度缺失的地方进行数据估计.最后通过仿真实验,将得到的估计投影图像与原始投影图像进行比较并分析.实验结果表明:在恢复投影图像的过程当中,采用线性插值误差更小,恢复的投影图像的精度更高,并且恢复速度快.

Incomplete Project Data Evaluation Based on Mathematical Method

In this paper,we mainly study the incomplete project data during the image restoration of incomplete project.For the incomplete project data,using the method of linear interpolation and spline interpolation to evaluate the datas in the local of deficient angles. Through simulation experiment,comparing the obtain project image with the original image and analyse the result.Experimental result shows that during the image recover,the error of the linear interpolation is small than the spline interpolation,the precision of the image recover is higer and the spreed is fast.
