摘要
通过引入空间自适应正则化参数,建立了离散的空间自适应全变分配准模型,并结合一阶泰勒展开式给出了有效的不动点求解方法.实验结果表明,由空间自适应全变分配准模型得到的图像的质量比全变分配准模型的更好,迭代时间更短.
A discrete spatially adaptive total variation image registration model is established by introducing spatial adaptive regularization parameters,and an effective fixed point method is given by combining the first-order Taylor expansion.Experimental results show that the image obtained from the spatial adaptive total variation registration model has better quality and requires less iterative time than the total variation registration model.
