我们提出了一个可分离的分解近似随机场的Karhunen-Loeve变换。我们表明,这个问题是有关的一组矩阵的联合奇异值分解,我们提供了一个有效的算法来计算it. Finally,我们说明了这个新的工具的图像表示和近似的兴趣。
We propose a separable decomposition approximating the Karhunen-Loeve transform for random fields. We show that this problem is related to a joint singular value decomposition of a set of matrices and we provide an efficient algorithm to compute it. Finally, we illustrate the interest of this new tool for image representation and approximation.
