| 摘 要： | 提出了一种利用多点地质统计法实现图像重建的方法.由于传统基于线性降维的多点地质统计法不能有效处理非线性数据,因此引入等距特征映射以实现非线性数据的降维,并利用条件数据以提高重建图像的质量.实验证明,该方法有利于提高图像重建的有效性.

| Abstract: | An image reconstruction method using multiple-point statistics (MPS)is proposed.Because traditional MPS methods based on linear dimensionality reduction are not suitable to deal with nonlinear data,isometric mapping is introduced in MPS to reduce the dimensionality reduction of nonlinear data using conditional data to improve reconstruction quality.Experiments prove that this method is helpful to improve the effectiveness of image reconstruction. |
