本文提出并研究了数字减影成象中自适应位移估计的理论和方法问题。适应性位移估计可归结为一种泛函优化
利用有限元的思想
本文提出了一类灰度校正模型
研究了新的准则函数和适应性分级搜索的新算法
给出了在医学DSA成象中的实验结果。
This paper deals with the problem of adaptive displacement estimation in Digital Subtraction Imaging. Its mathematical model is given
in which it is considered as a problem of functional optimization. Based on the idea of finite element method
a family of models for correction of gray level variation is presented. New criterion functions and adaptive hierachical searching algorithms are developed. The experiment results in medical imaging (DSA) are reported.
